1. The minutes of the thirty-first LHCC meeting (LHCC 97-61 / LHCC 31) were approved without amendment.

The Director General reported the following draft Minute of the 20 November 1997 meeting of the Research Board:

E. Iarocci reported on the discussion of the FELIX proposal (LHCC 97-45 / I 10), which led to the conclusions reported in the draft minutes (LHCC 97-61; LHCC 31). The Research Board discussed these conclusions thoroughly, taking into account the large material and manpower cost of constructing an additional interaction region, which could only be done at the expense of some other activity in the CERN programme. The Research Board upheld the decision of the LHCC not to encourage the FELIX Collaboration to proceed to a proposal, and noted that a full coverage experiment would not be part of the first generation LHC programme, despite the potential physics interest.

2. REPORT FROM THE CMS REFEREES

The committee heard a report from the CMS referees, concentrating on preliminary reactions to the Technical Design Reports for the muon system and electromagnetic calorimeter. The referees plan to make a full report at the next meeting of the LHCC.

3. REPORT FROM THE ATLAS REFEREES

The committee heard a report from the ATLAS referees covering their recent review of calorimeter systems, undertaken with M. Calvetti and J. Strait as consultants.

4. REPORT FROM THE LHC-B REFEREES

The committee heard a report from the LHC-B referees covering progress on Hybrid Photo-Diodes and planning for the forthcoming Technical Proposal.

5. REPORT FROM THE ALICE REFEREES

The committee heard a report from the ALICE referees covering progress on several recent milestones, concerning silicon detectors, TPC, Photon Spectrometer, Zero Degree Calorimeter, muon arm dipole magnet, and trigger / data acquisition.

6. TEST BEAMS ETC.

E. Tsesmelis presented the SPS fixed-target programme for 1998, which has now been accepted by the users. He also described the use of the LEP pre-injector experimental area for tests using electron beams and synchrotron radiation. He summarised current plans for dealing with the effects of LHC civil engineering work on SPS operation.

7. PHYSICS WORKSHOPS ETC.

G. Altarelli described plans for a workshop on the Theory of LHC Processes to be held on 9-13 February. The LHC proposes to hold a one-day workshop on Standard Model Physics on 21 October: details will be announced at a forthcoming meeting of the LHCC.
