Plans are taking shape to form a new group to coordinate and stimulate R&D on monolithic and vertically integrated pixel detectors for scientific applications in high-energy physics and beyond. In a joint message, the directorates of CERN, KEK and Fermilab have offered their support. They suggested the formation of a regionally balanced coordination board to take this forward. From discussions in recent reviews and workshops, we think there is an opportunity for the many efforts underway worldwide to benefit a larger community. We already have strong collaborations for the development of vertical integration and monolithic active pixel sensors (MAPS). The new world-wide effort would build upon the existing collaborations and open the technology developments to other scientific areas. We will discuss how best to achieve this at upcoming meetings. Our suggestions will then be comunicated to the directorates of CERN, KEK and Fermilab.

The international time projection chamber (TPC) team that works on R&D for future ILC detectors used to have a bit of a running gag. Somebody would proclaim that “the field cage will arrive next week” and everybody else would chuckle because week after week it didn’t arrive. Chuckling days are over now: after several years of planning the cage for the large TPC prototype, ordering it from industry, checking the quality, rejecting parts of the product and reordering, the nearly one-metre-long barrel with an inner diameter of 72 centimetres has finally arrived at DESY in Hamburg. First tests indicate that it will finally meet the team's high requirements.

Three concept groups have responded to the call for Expressions of Interest: ILD, SiD and the 4th concept group. Now we can go one step further, namely the common task groups will be formed by the members of each of these groups.

Have you ever used a map to find an electron? Not possible, you say? Think again. Spell it slightly differently – MAPS – put it into an electromagnetic calorimeter, and you may well be able to track an electron in a calorimeter and see the single electrons in a particle shower. With a spatial granularity of 50 microns square– that's 50 thousandths of a millimetre – a potential sensor, called MAPS or monolithic active pixel sensor, for an ILC detector's digital electromagnetic calorimeter could be an efficient alternative to existing silicon technology. A UK-based group is currently evaluating how suitable this technology is for a calorimeter optimised for particle flow, with a view to seeing how efficient, reliable and cost-effective it is.

Digitisation - a key word that could lead to smaller and simpler detectors. Two weeks ago, at Saclay, France, the CEA Time Projection Chamber group of Paul Colas proved it could build a digital TPC for the ILC. A truly collaborative effort, this breakthrough could significantly reduce the cost and simplify the implementation of this sub-detector.

The cacophonous tune of cicadas serenaded the physicists at last week’s Department of Energy and National Science Foundation review of the US Detector R&D Programme for the International Linear Collider. Harry Weerts, the High Energy Physics Director at Argonne National Laboratory, where the review took place, vividly remembered the last time the cicadas visited --17 years ago when another detector milestone was in the making. “I remember it well because we were commissioning the DZero detector at Fermilab,” he said. “I’m looking forward to the next time the cicadas come around and seeing what the world looks like then.”

The calorimeters for the ILC detectors have to show excellent performance if researchers want to fully exploit the physics potential of the ILC. Many processes that are unique for the physics programme of the ILC are characterised by multiple-jet production that can be reconstructed by new calorimetry techniques to very high energies with unprecedented precision. The goal is to improve the jet energy resolution already achieved by a factor of two to fulfil the physics requirements the best possible way. Hence we need to develop these novel technologies and show that they work by ‘proof of principle’.

Not many people see an immediate connection between exploring the origins of the Universe and finding cancer cells. Nicola d'Ascenzo and his colleagues sure do. In their work to test photo sensors as potential candidates for an ILC hadronic calorimeter they have come across a sensor that could be extremely interesting for positron emission tomography or PET, an imaging techniques that identifies cancerous cells in a body by detecting emitted gamma rays.

Peeling paint? Leaky roof? No problem. Say the words “test beam facility” to a physicist, and the opportunity to collect real physics data will wash away any aesthetic issues. Literally.

When scientists take their detector prototypes to a test beam they enter a parallel world. Many basic needs are put on hold - the need for sunlight, regular meals or eight hours of sleep, for example. What counts is the beam time: you have three days, weeks or months to test your equipment, and you have to make the best of it because you might not get another chance. A team from Japan and Korea have just reached the halfway point of their time in the DESY test beam, calibrating, checking and recording data with their electromagnetic calorimeter prototype.
