Summary of the impact
As standard commercially-available imaging systems were unable to deliver
the performance
necessary for our astronomy research programmes, we formed a partnership
with Andor
Technology to develop two new specifically-tailored novel imaging systems:
one to allow high-speed,
high cadence imaging over an array of detectors whose capture times were
precisely
synchronised (for solar research); one to combine large format CCD
detectors with a
thermoelectric deep cooling design, removing the need for a separate,
expensive cooling system
(for exoplanet research). This partnership contributed to the development
of new imaging products
within Andor Technology (2008 — present), for which the company estimates
a current total
revenue value of over £1.7M per year. It has also helped Andor to maintain
a leading position in
the scientific camera market on a global scale, via the press and industry
coverage obtained for the
new technology development.
Underpinning research
Solar research:
High cadence observations of astronomical sources has been a growing field
within astrophysical
science and there is a clear need for such observational data in solar
physics. Many solar research
topics involve the observation of phenomena over small sizes (few tens of
km) and short
timescales (one second or less), in particular those related to the
variable Sun and its influence on
the Earth. Solar flares and other events can seriously affect satellite
communications, GPS
systems and power grids, the most famous example being the blackout in
Quebec in 1989, which
cost the Hydro-Quebec power company alone over $10M.
In the mid-2000's, Profs Mathioudakis, Keenan and collaborators realised
the need for the
development of specialist equipment to allow progress in the understanding
of solar phenomena at
a much greater level of detail than previously achieved [1, 2]. Their
development of high-cadence,
multi-wavelength imaging systems, in collaboration with Andor Technology,
has allowed unique
high-frequency imaging of the solar atmosphere. In particular, the Rapid
Oscillations in the Solar
Atmosphere (ROSA) instrument provides images of the solar atmosphere
simultaneously at 6
wavelengths, at a rate of up to 200 images per second per wavelength, with
a resolution of better
than 100 km [3]. ROSA was part-funded by a PPARC grant for £246K awarded
to Keenan and
Mathioudakis in September 2007, followed by STFC grants for £99K in August
2009 and £51K in
August 2012 and an FP7 Integrated Infrastructures Initiative grant in
April 2013 for €223K to
Keenan and Mathioudakis to support ROSA operations. Since its successful
deployment in August
2008, ROSA has been extensively used to investigate high-frequency waves
in the Sun. It is now
one of the top requested instruments at the Dunn Solar Telescope in New
Mexico, the prime US
facility for solar ground-based observations. Mathioudakis and Dr Jess
subsequently won the
inaugural Andor Insight Award for scientifically-captivating imaging
obtained with Andor equipment
(November 2011), which attracted extensive publicity, e.g. see:

Exoplanet research:
One of the most important scientific advances in recent years has been the
discovery of
exoplanets, i.e. planets orbiting stars other than the Sun. The best
method for discovering
exoplanets is through transit surveys (watching for the dip in the light
from a star resulting when the
planet passes directly between the star and the observer during its
orbit). When coupled with
follow-up observations, such transit surveys provide measurements of
planetary masses and
densities, and potentially spectroscopy of planetary atmospheres. The most
successful Earth-based
transit discovery systems to date have been the Andor camera-based
SuperWASP (Wide
Angle Search for Planets) facilities, whose development was led by Prof
Pollacco and colleagues
(note that Pollacco left QUB in August 2012). Although the SuperWasp
project officially began in
2000/2001, its genesis can be traced back to the mid-1990's when, together
with the team at ING
in La Palma, Pollacco developed a series of cameras with wide
fields-of-view, known as CoCam.
When it became clear that these cameras might allow exoplanet transits to
be discovered, plans
were developed to build WASP (Wide Angle Search for Planets) in 1999/2000.
Observations using
WASP in Summer 2000 demonstrated the ability to detect planetary transits,
thus prompting further
system developments and the creation of the SuperWASP-North and -South
projects [4], funded
by an initial PPARC grant for £105K to Pollacco, Keenan and Fitzsimmons in
April 2001, and a
subsequent PPARC award for £464K in April 2008 to Pollacco and Keenan to
operate the
SuperWASP-North facility. To date, these facilities have led to the
discovery of >90 transiting
exoplanets, with more to be announced [5, 6]. More importantly, in terms
of impact, the
development of these cameras and their world-wide visibility through the
WASP exoplanet
programme has led to significant sales for Andor in this market. The
societal impact has also been
large, with many press and TV-radio articles, including BBC reports, e.g.

Details of the impact
ROSA (Rapid Oscillations in the Solar Atmosphere):
The detectors in our SuperWASP and ROSA instruments were developed in
collaboration with
Andor Technology plc, one of the world leaders in detector technology,
which employs over 300
people in 16 offices worldwide, and distributes its products to 10,000
customers in 55 countries.
Our successful partnership with Andor allowed them to identify large
format CCD and high-speed
ultra-sensitive EMCCD scientific cameras as a growing market for
astronomical applications, as
they were unaware of the increasing importance of high cadence observing
in astrophysics
research. In addition, the partnership allowed Andor to become involved in
the European Solar
Telescope (EST) Consortium, and provided access to EU/FP7 funding for
Andor of €81K (2008 - 2011)
for a preliminary detector Design Study for the EST. This in turn has
potential applications to
other solar telescope designs around the globe, such as the Advanced
Technology Solar
Telescope (ATST) in the USA and the National Large Solar Telescope (NLST)
in India. Most
importantly, the drive for science excellence in our programmes pushed
existing detector
technology to its limits, and was directly responsible for Andor's
development of these large format,
low noise, high-speed cameras. Andor has now been identified (by the EST
and ATST Consortia)
as one of only two companies worldwide which have the capability to
provide cameras that can
meet the stringent science requirements of the next generation of solar
telescopes (i.e. large
format, synchronised and fast readout).
For ROSA to operate successfully, it has been necessary to solve the
problem of accurately
synchronising up to 6 cameras at high cadence, so that all images are
obtained at exactly the
same time with an accuracy of a few microseconds. Andor worked with
Mathioudakis and Keenan
to develop the synchronisation hardware and software infrastructure to
achieve this. Following its
successful development, this directly expanded Andor's understanding of
high bandwidth data
handling and multi-camera synchronisation, identified as a key future area
in terms of providing
`added-value' to camera systems. In particular, high bandwidth solutions
are highly complementary
to next-generation scientific CMOS technology, an area of innovation that
is presently being
spearheaded by Andor. This new ground-breaking technology offers the
ability to acquire large
format data at very fast frame rates with extremely high sensitivity and
is already resonating with a
broad diversity of scientific applications, including in biophysics (e.g.
investigating
neurotransmission at individual synapses in brain tissue), drug discovery
(e.g. imaging biological
reactions such as drug binding) and high-cadence astronomy (including
solar physics).
Our partnership with Andor has directly led to the development of imaging
products
comprising o f camera (or multi-camera) systems combined with high
bandwidth data handling
and real-time processing units. The sales of these products generated over
£1.4M in 2012,
and is estimated by Andor to grow to more than 300 systems per year in the
next 5 years,
corresponding to a revenue of £3.8M per year. This has also helped Andor
to maintain a leading
position in the scientific camera market on a global scale, particularly
in the consistently growing
and relatively well-funded area of astronomy.
Super-WASP and the Next Generation Transit Survey (NGTS):
We have collaborated with ANDOR on the development of large format,
deep-depleted CCDs
needed for the Next Generation Transit Survey (NGTS) project. Although
NGTS will use large-format
deep depleted CCDs from e2v Technology, (Chelmsford), it is the Andor low
noise camera
architecture and deep cooling technology that makes these devices usable.
Building on the
heritage of the SuperWASP project, we conducted a prototype experiment on
La Palma
(November 2009 — March 2010) using Andor's 1K x 1K iKon-M 934N BR-DD
deep-depleted CCD.
This experiment proved the viability of high-precision photometry with
such technology. Our results
led directly to the development of a new camera product (the larger format
2K x 2K iKon-L 936
deep-depleted CCD) by e2v-Andor-QUB for NGTS. As the largest format,
deep-depleted cameras
that only need thermoelectric cooling rather than bulky and expensive
cryogenics, this is a major
advance in professional imaging systems. These devices have now become
part of the Andor
product portfolio. Andor Technology is currently the sole company
marketing these devices, and
sales have amounted to greater than £500K in only 18 months since the
product came into the
market.
We note that our case study clearly provides impact as defined in Annex C
of the Guidance on
Submissions, namely under paragraph 5 — change or benefit to the
activities, performance, policy
and process of an organisation. Specifically, our partnership with
Andor led to the decision to
develop new imaging systems and the resultant revenue from these.
