1. The minutes of the 1st meeting held on 17th October 1996 were approved.

2. There were no matters arising.

3. Report to the LHCC

Peter Sharp presented his report of the first meeting to the LHCC and reported on the issues raised by the LHCC. The LHCC had formally expressed their thanks to all those involved in the organisation of the first two workshops.

4. Review of plans for the 1997 LEB workshop in London 

Geoff Hall described the work of the local organising committee and the plans for the workshop to be held at Imperial College from 22-26 September 1997. It was noted that the dates chosen clashed with the IEEE Real Time Conference to be held in Beaune but given the other constraints this could not be avoided. Every effort will be made to co-ordinate the programmes of the two meetings. The Board discussed the proposed programme for the workshop, and made suggestions for several improvements. It is proposed to have a number of parallel working groups which will focus on the specific needs of the different systems involved in LHC detectors and to include a number of plenary panel discussions to ensure that everybody at the workshop has the opportunity to learn from the proceedings of the other working groups. The requirement for poster sessions will be discussed at the next meeting.

A poster had been prepared and this together with the call for papers would be mailed to everybody who had attended either of the previous workshops and to a comprehensive list of academic and industrial organisations.

The Board reviewed the proposed costs and approved a meeting fee of ~£200. 

CERN had agreed to be responsible for the proceedings and Catherine Decosse had agreed to act as editor again this year.

At the next meeting the board will return to discuss the programme. All members were asked for suggestions for topics and speakers for the plenary sessions, and for convenors for the working groups and panel discussions.

5. Quality Management Systems

Steve Quinton presented the fundamental issues involved in Quality Management Systems and emphasised the differences between Product Assurance and Quality Systems. In the discussion that followed the Board agreed:

- That some form of Quality Management System like ISO 9001 ) was very desirable and probably essential if LHC was to be constructed, efficiently, on time and within budget.

- That there were a large number of cultural problems to be overcome in persuading the Particle Physics Community to adopt such systems.

- That it was very important that all levels of the community embraced the commitment to Quality Management.

- That the LEB would pursue this issue as its top priority.

6. Proposal from CERN to establish a testing facility.

The Board welcomed this proposal from CERN and the opportunity to review the requirements of the LHC experiments for testing facilities and to develop a strategy to ensure that the community has access to the most appropriate facilities. The Board concluded : 

- That a complete list of the microelectronics chips under development by each of the experiments would be very useful to the whole community.

- That the list of chips should also identify With some suggestions added by after the meeting) 

1. The name and description of the chip

2. The design authority

3. The collaborating institutions

4. The radiation hardness requirement

5. Any other special features

6. A proposed testing strategy

7. Any on chip self test features

8. The total number of chips required for LHC.

9. The approximate cost of the design and production process.

- That each experiment should identify any testing facilities available to the collaboration and whether they consider more testing facilities are required. 

- That each experiment should distinguish between testing to verify the quality of the design and production testing facilities.

- That the facilities that exist in National Laboratories should be identified and there availability to the wider community confirmed.

- That a cost benefit analysis is essential for large investments of this type.

7. Recommendations of VMEbus standardisation

The Board welcomed this initiative from CERN and confirmed the importance of establishing standards for use at LHC which were based on widely accepted industry standards. Before making any recommendation the Board would like to obtain the reaction of the LHC experiments to this proposal.

8. Report on RD9

The Board accepted the final status report of the RD9 collaboration and thanked the spokesman and the members of the collaboration for their thorough analysis of this technology.

9. A Proposal to study Radiation Tolerant Electronics - P63

The Board welcomed this proposal and confirmed that the understanding of the requirement for radiation tolerant electronics at LHC was a very high priority. It was agreed that the present proposal lacked a specific focus and that it was important to ensure that all of the LHC experiments considered this problem and comments on their requirements. The proposal will be considered at the next meeting. It was agreed that more than one referee would be appointed to ensure that all aspects of the problem were considered.

10. Plans for future meetings:

March 11 1997 

Final status report from RD29 - DMILL
Open presentation on Quality Systems at LHC

Further discussion of :

P63 - Radiation Tolerant Electronics
London workshop preparation
Quality Management Systems
Testing facilities
VMEbus standardisation

May 30 1997

The date of this meeting will be changed as it clashes with the Elba meeting. It is also the first meeting after the deadline for abstracts for the London Workshop and will probably need to be a two day meeting to allow a review of the abstracts. 

Other items will include:

RD12 TTC). Final Status Report

RD16 Fermi) Final Status Report

RD19 Pixel) Status Report

RD23 Opto-electronics) Status Report
