1. RICH TDAQ STATUS F. Bucci, R. Ciaranfi, M. Lenti, M. Piccini, C. Santoni TDAQ WG, 02/09/2014 02/09/2014 F. Bucci 1

2. PMTS INSTALLATION Installation of PMTs on the Jura and Saleve lodging disks completed Looked at the signal shape and measured the rate of each PMT Jura lodging disk Saleve lodging disk 02/09/2014 F. Bucci 2

3. PMTS TEST The disks were installed on a light tight box and enlighted with a laser to look for dead channels The HV cables of the PMT dividers were plugged in the HV distribution boards 02/09/2014 located at the same distance as in the experimental area F. Bucci 3

4. FE STATUS AND TEST New FE board prototype is ready Two different setup still under testing Performances look promising Order to be placed within the end of the week Full production should be finished at the end of September The arrival at CERN is foreseen at the beginning of October FE boards schedule tight but still feasible 02/09/2014 F. Bucci 4

5. SCHEDULE OF INSTALLATION AND TEST OF PMTS AND FE All the electronics but the FE boards will be carried to CERN next Monday. In the following two weeks the PMT lodging disks will be installed in ECN3 and the HV cables will be plugged. The last week of September the full chain of electronics will be tested by using a FE board prototype and enlighting the PMTs disk with a laser. 02/09/2014 F. Bucci 5

6. RICH Trigger Firmware Status Two different firmware versions has been developed: RICH version GPURICH version Most of the firmware is common between the two versions PP FPGA SL FPGA RICH RICH HITS CLUSTERING CLUSTERS MERGING CHANNELS INFO HANDLING GPURICH CHANNELS INFO HANDLING GPURICH 02/09/2014 F.
