    The cabling of the gas Cerenkov for the R-HRS is completed thanks to Jack. The cables have also been tied up to the detector. I also worked on the electronics. The cables have been connected to the LeCroy 4413 discriminator and patch panel for the ADCs as follows:

    From the LeCroy 4413 module, the signal is also sent to a LeCroy 4518 delay module, from which the signal goes to a TDC and scaler module. Tomorrow, I will verify to which ADC and TDC the signal is going. I also need to create the Cerenkov ADC sum.
