What we have in Helwan HV Power system SY 2527 Universal Multichannel Power Supply
System with HV modules and High Voltage Power Supply (0-3 KV)
(ORTEC 456) for scintillator.
LV system --> SY 2527 Universal Multichannel Power Supply System with LV modules.
GAS system ..> Gas Mixer, Freon bottle and Ar-CO2 bottle. We need to switch to RPC standard mixture.

Our plan Transfer the hardware to Helwan.
Complete the installation of the all hardware needed.
Complete the set-up of the telescope (hardware and software).
run the DAQ system (the same used in GIF) and applied the necessary modifications.
test the RPC performance with cosmic muon (spare chambers from CMS Endcap have been requested to CMS- RPC collaboration).
