Detector Workshop
9 February 2000 at CERN

    Start meeting:               09 Feb 9:00
    End:                         late afternoon
    Place:                       13-2-005


    

General remark:

Let us recall the main results from the last detector meeting
at CERN, December 17:

1) Coil: Length will be 9.2m, because of field homogeneity 
         requirements for the TPC. 
         (This will be reconsidered at the February meeting
         in the light of new info on dB/B as function of z 
         which will become available).

2) Intermediate Tracker: Two layers with ca. 10\mu 3d-resolution 
         at approx. radii of 15 and 30 cm. This ensures best
         momentum resolution and efficiency for secondary vertex
         finding for the different options of the vertex detector.

3) Calorimeter: Two options will be considered:
         a) Shashlik for the electromagnetic and hadronic parts 
         (the CDR version already implemented in BRAHMS), and 
         b) SIW for the electromagnetic part together with tiles 
         for the hadronic part (to be implemented within two months),
         as the preferred baseline option.
