acknowledgment :

EST-DEM has a long record of an extensive and productive collaboration with the research projects.

It is generally felt that EP received a top quality treatment from the people in this group, and a lot of expert support in all fields : design materials, surface mounting, multilayer PCB's, photolithography, electronics assembly.

Such a group is felt to be essential inside CERN

In general DEMAC should help in : - enhancing the Management of EST-DEM - linking the activities with the priorities of the physics program

EP-DI-DDL-VV 4

ATLAS

PCB manufacturing section :– Special PCB boards or hybrids– extensive use of capacity to build multilayers PCB’s – transfer some technologies to industry

Assembly workshop :– prototype board assembly– help on price enquiries or call for tender– wish : contracts with few companies for fast assembly

work Lay-out workshop :– turn-around per year : 10 CHk– wish : improve transparency on pricing policy– lot of design work in the two/three years to come

EP-DI-DDL-VV 5

CMS

first priority for the coming 6 months : the Tracker.

Several weeks of layout work, followed by production and components assembly of tens of PCB’s ( memo from P. Siegrist / EP-CMT ) cabling previsions given for the 6-12 months to come

EP-DI-DDL-VV 6

ALICE FE bus of Silicon Pixel Detector ( SPD)

- low-mass multilayer polyimide / aluminum bus- vital necessity for ALICE SPD- special technology, no interest from outside Companies- quote given by EST-DEM

HMPID pad photo-cathodes- about 100 PCB’s over the next 2 years- expertise developed in EST-DEM needed for this production- 50 PCB’s standard multilayer technology with special requirement on flatness (60 men.days)

Silicon Strip detector (SSD)- 3 series for prototypes (100-150 pieces each) : copper-Upilex cables, PCB’s on ceramic, PCB’s on standard support

EP-DI-DDL-VV 7

LHCb

most of modules are in principle fully designed and produced in external Institutes

few additional requests for PCB layout and assembly of large highly populated cards

in 2001, about 10 prototypes

need : consultancy on board production and testing in external companies

EP-DI-DDL-VV 8

GEM

development and production 300 gem delivered to HERA-B Tracker COMPASS remaining needs :– 2001 runs : 14 detectors– 2002 runs : 10 detectors

development and optimization :– TESLA, STAR, PEP-N– medical imaging– neutron detection– X-ray polarimetry for astrophysics– plasma diagnostics– gas photomultipliers

technological support and Collaboration from EST-DEM are primordial

EP-DI-DDL-VV 9

NA-60 technological support from EST-DEM essential to this experiment top quality treatment up to now feel some degradation due to shortage of manpower top priority are hybrids for microstrip planes :– October run– critical, present situation in schedule not acceptable

HARP essential support from EST-DEM only few more minor componentsR & D projects (Si-facility) number of required components is small need fast turn-around concerned about pricing ( R & D budgets are small), 80 CHf / hour + overhead

EP-DI-DDL-VV 10

Comments from Microelectronics group (EP)

EST-DEM should be able to : track evolution towards future sophisticated technologies– low-mass– radiation tolerance– high track-density hybrids – circuits operated at cryogenic temperatures

preserve and boost local expertise ensure flexibility and adaptability to special requirements this technological support should stay on a solid base :– concentrate on high-tech– balance correctly basic tech by efficient outsourcing of

standard work

EP-DI-DDL-VV 11

Comments and suggestions

1.- PCB workshop management versus technical expertise

a technical expert should not be loaded with the management of the workshop. We recommend to have a dedicated manager for the PCB workshop

Tasks : - promote transparency in scheduling and costing• pro-active management in direct discussion with experiments

understanding of timescales• dialogue to develop a good perception and mutual positive

attitude• organize monitoring data, public records and statistics on jobs

and costing• transfer of technologies to Companies

in parallel, around the technical experts, build a Team including Students, Project Associates, outside people attracted by the high-tech expertise and by the developments.

2. Special technologies

Several technologies are quite special and of unique expertise these should not be endangered by any run-down of EST-DEM it is essential to maintain enough people in the group, for the workshops and for the software. the high-level technical expertise is essential. Such a level should be maintained in a domain where it takes a long time to form a person. several physics groups have felt the decline of manpower on their projects : turn-around slower, crisis with timescales we repeat that this support is essential to the whole physics programme and should not be run-downed.

EP-DI-DDL-VV 13

3. Strategy CERN us outside

a mechanism should be implemented to have a smooth transistion for “standard” projects to be outsourced. Transfer of data from CERN to Companies arguments for Inside design / production :– fast turn-around– phototyping– special technologies– record of data, history, storage, EDMS

help required in contracs with outside Companies identify Companies with fast turn-around, for cabling special productions should stay in house, like for example aluminum polyemide buses or GEM developments, etc...

4. others

pro-active collaboration between EST-DEM, C. Benvuti’s group, EP-MIC group, new EP-Division Si-facility should be encouraged by the EST-DEM Management. For their jobs, the uses should be told how long it takes, how much it costs, so a comparison with outside Companies be possible. we acknowledge also that users should help with better planning efforts from their side how to handle external users (outside Universities, recognized experiments) largely scattered? Keep flexibility for small items in developments
