Minutes of the CALICE-UK Steering Board phone meeting, 09/06/04 =============================================================== Present at Birmingham: Chris Hawkes, Nigel Watson Present at Cambridge: Mark Thomson Present at DESY: Matthew Wing Present at Imperial: Paul Dauncey Present at SLAC: Roger Barlow Present at UCL: Jon Butterworth Minutes: Paul CALICE(-UK) status: Paul gave a short summary of the status of CALICE and CALICE-UK (see slides). There were few volunteers to give the CALICE status report at the LCUK meeting in Lancaster on 30 June, so Paul will discuss this with Dan Bowerman (who has not yet said no) and one of the two of them will give it. There was agreement on the proposal for transfer of funds from travel to equipment and RAL effort so Paul will organise this. MoA draft: There had been several comments on the previous MoA draft 2. There are several changes to draft 5, in particular in Annex 1 for the CALICE collaboration organisation. Draft 5 is not yet agreed by the CALICE Steering Board; Paul edited in the latest changes following a discussion with Rolf Heuer (the SB chair). This draft was supposed to be discussed at DESY around the PRC on 27 May, but this did not happen. It is now scheduled to be discussed at the CERN meeting on 28 June. Future plans: As discussed at the last meeting, there are several potential directions which we could aim for with regard to a long-term LC calorimetry bid. The timescale is more relaxed than originally thought. Paul talked to Jenny Thomas last month and she said submitting another SoI is not required. (This would have been required within a month if needed, in order to be considered by SciComm and have us invited back before the end of the year.) We should give Janet Seed a warning that the bid will be going in later in the year so she can think about the budget side, but this can be a little later, when we have a firmer idea of cost. Numbers tend to get set in stone within PPARC so we would need to aim high at this early stage. The R&D items which are being considered are: o Plastic semiconductors: This was considered to be an interesting area and people had been encouraged to contact their Departments to find out if they had local expertise. Mark said the Cavendish had a large group in this area. He had had some contact already but would have more time after the exams were completed. His preliminary discussion had already raised the scale of what we want to do as an issue. Nigel reported that Birmingham did not seem to have much research in this area so things did not look promising there. He was also planning to ask at RAL ID. At UCL, Matthew had sent some emails but chasing them up was hard while he was still at DESY. Paul had not done anything beyond his original contact with the active group at Imperial; he will also follow this up after the exams are finished. o DHCAL: Matthew had had several email exchanges with Jose Repond on the subject of us getting involved in the DHCAL. Jose had been quite enthusiastic as he is looking for immediate funding for the readout of the CALICE DHCAL. This would be yet more throw-away short-term electronics and it is very unlikely we would get funding (or have the effort available) to do this. Hence, it is not clear whether the DHCAL idea is viable; Jose is not thinking so much about the longer term yet. Paul will chase this up further at the CERN meeting on 28/29 June. o FE/BE DAQ electronics: Paul has done little concrete on this since the last meeting. Having looked at some of what has been done for the LHC, it seems clock distribution is quite advanced there so it may be hard to really define a new program for the LC, particularly before the machine decision as the difficulty of the clock distribution depends strongly on the timing. Jon had discussed ideas with the UCL engineers and was thinking more in terms of the FE (on-detector) electronics and how that could be made very flexible in terms of FPGAs, etc. The main argument could be investigating handling large amounts of data due to the high channel count. This seems a profitable area to consider further and a brainstorming meeting to go through this with some engineers was agreed (see later). o MAPS; Paul outlined a possibility for using MAPS (see discussion document). One motivation here is that the UK is a strong leader in this field and PPARC are keen to have some real applications from the R&D which has already been done. To be useful, we would have to demonstrate that the very fine (digital) pixels of MAPS would give better pattern recognition that the pads and so that there could be less layers (and hence reduced cost). This will need quite a bit of simulation work. This was seen as more of a longshot but Paul will discuss this further with the MAPS group. The simulation experts should at least consider whether MAPS could lead to any improvements. AOB: The people who said they would go to the CERN meeting on 28/29 June were; Paul, Dan Bowerman and Catherine Fry from Imperial and David, Chris Ainsley and George Mavromanolakis from Cambridge. Jon will be at CERN for the Atlas SCT week and so may be able to attend some of the sessions. Next meeting: The FE/BE DAQ brainstorming meeting should be held at UCL while Matthew is there in late July. The next meeting for the CALICE-UK SB could take place there on the same day. Wed 28 July was chosen, with the electronics discussion in the morning and the SB meeting in the afternoon.
