Subj:	Beam time 1998 request

    Dear  Mathias,
sorry for being so late with the request, but our plans are not very clear , 
especially untill this year test finished. So, please regard the request below
as preliminary.
Regards,        Yuri.
============================================
       COMPASS user request for test beam time (v1.0)
       ----------------------------------------------

1. contact person:      Yuri Khokhlov.

2. type of detector to be tested:   drift tubes

3. period foreseen for the tests:    2-3 weeks

4. do you handle with flamable gases (yes, no):  yes

5. longitudinal size of the detector (including frames etc):
          [cm]:                     50 cm
          [radiation lengths]:      0.06
          [interaction lengths]:    0.015

6. transverse size of the detector [cm]:    60*250

12. readout electronics:        TDC 

13. estimated amount of rack space for the readout 
    electronics:    1/2 of crate

14. What is the maximum tolerable amount of material 
    upstream your detector   for            muons       hadrons
          [radiation lengths]:              1.-10.       0.20
