======================
MPI-Munich: Laci Andricek

The current status of the double sided module development is:
 
1.) The thermal model is assembled and a simple cooling system is
    set up. The electrical connections to the heating foils
    and the PT100 are almost ready and we expect to measure
    the temperature-distribution on the module during the coming
    days. This distribution will be measured first in a 
    thermally isolating box without convection and second in
    a climate-box at an ambiente temperature of -5 degC. I'll
    put a summary of the measurement results on our web-page
    as soon as possible.
 
2.) The amount of material is being optimized. Extensive
    thermal simulations with different width of the CFC-frame
    were done last week at NIKHEF. I expect to get the results
    on Monday (November,18.). They will again be put on the
    web as soon as they are summarized.
 
3.) An optimized module in terms of mass an stability is in preparation.
    Measurements of the thermal distortion and the integration of an
    electrically working module with SCT128 readout will follow early
    next year.
 

UK-Forward: Neil Jackson

  Measurements with the thermal module are in progress and we expect to go
to Oxford this week for the distortion tests. We hope the electrical
module will be assembled around 1/12/96.
 
 
Japan:  Y.Nobu UNNO

  Measurement of the two (end-tap and centre-tap) thermo-distortion 
modules were carried out at Oxford.  (The modules and the PG-on-Glass
support base were shown in the Oct Engineering meeting at CERN.) 
Preliminary results of distortion patterns and temperature distributions 
were posted on a web page.  

  Preparation of the electrically working module is proceeding together
with UCSC and LBNL:
 - One (-side) of fully loaded Kapton hybrid was sent from UCSC to KEK.
   Three more hybrid (partially loaded) from UCSC will be stuffed and
   wire-bonded in Japan.
 - BeO hybrid base was sent from RAL to KEK
 - Glass pitchadaptors were fabricated in Japan.  KEK will supply a few
   to Melbourne in response to its request.
 - A new batch of nn80AC detectors are about to be delivered (8 detectors 
   for two modules).  KEK will supply another 8 detectors to UK-Barrel
   group in response to its request.
 - PG core are being machined.  We use PG700 because of the availability
   this time.
 - Assembling fixtures are being delivered
 - Wire-bonding will start for the first hybrid - detector in this week.
 - Two nn75AC detectors were supplied to LBNL for an assembly of single-
   sided module, centre-tap, with LBNL ceramic hybrid (AlN), to test
   the wire-bonding of the bridged hybrid and the electrical noises.  

  Detector irradiation:  2 newly designed 75 micron pitch double-sided
detectors, and 3 new nn80AC detectors were sent for the CERN PS November
irradiation.  In addition these, remaining 3 nn75AC detectors are 
being irradiated (in cooperation with Cambridge group, especially, Dave
Robinson.)

UK-Barrel:

  Distortion measurement are being carried on for an end-tap and a 
centre-tap module at Oxford.  Trying to use both a UK-built support
base and the KEK-build PG-on-Glass base.
  Electrically working modules: 

  - Pedja is at UCSC and assembling one double-sided Au-3micron/BeO 
    hybrid for the end-tap, and two single-side loaded BeO hybrids for 
    centre-tap modules.
  - Delivery of MICRON nn80AC detectors are delayed; requested KEK to
    provide Hamamatsu nn80AC detectors for module assembling.
