The REVISED schedule for the 2003 experimental runs at the CERN-EC Reference Field
(CERF) facility is the following:
                             
Wednesday 16 July at 16:00 to Wednesday 23 July at 10:00

and 

Thursday 28 August at 10:00 to Wednesday 3 September at 8:00.

As in the past few years, the beam will be 120 GeV/c positive particles.

Please note that there still is a small chance that the period of one or both runs is moved by one or two weeks.

PLEASE SUBMIT YOUR REQUEST FOR BEAM TIME BY 30 APRIL.

In your request, please state what type of detector you wish to expose (active or passive), the irradiation position, the number of 8-hour shifts you need, the estimated integrated dose equivalent or dose equivalent rate you need and your preferred period (July or August). Please note that in the case of overcrowding of one period we may have to reschedule some of the requests to the other period.

Please remember that the irradiations can take place:

- on the top shielding, target under either 40 cm iron or 80 cm concrete;
- on the side shielding, target behind either 80 or 160 cm concrete.

There are 16 + 16 reference positions on the top and 8 + 8 on the side.
According to the position, the maximum dose equivalent per PIC-count (with 1 PIC-count equal to 2.2E4 primary particles incident on the copper target) and the range of dose equivalent rate available are the following:

40 cm iron: 1-2 nSv/PIC, dose equivalent rate 25 microSv/h - 1 mSv/h
80 cm concrete: 0.3 nSv/h, dose equivalent rate 5 - 600 microSv/h.

Please send your request by (preferably) e-mail to Marco.Silari@cern.ch or Evangelia.Dimovasili@cern.ch, 
or by fax +41 22 7679360 (PLEASE NOTE CHANGE OF FAX NUMBER).
