Abstract
High-pressure gas modules with cylindrical ionization chambers for a V ery Forward Calorimeter (VFC) were constructed and tested in the U-70 electron beam of IHEP (Protvino). The read-out amplifiers were used in a remote mode (3 m long cables were used to connect the detector to t he amplifier). The module performance was tested in the shower energy range 10-30 GeV employing different gas mixtures (Ar + CH4, Ar + CF4 a nd pure CF4) at the pressure of 20-40 atm. The energy resolution sigma (E)/E = 18% is reached at the angle of 5.7 degrees for 30 GeV incident electrons. The design was found to be adequate for a future use at LH C.
