V.Duk, INFN Perugia CHOD/NHOD FE CHOD: 4 LAV FEE boards 4 x 32 = 128 channels, 256 channels in the TEL62 (2 TDCBs) NHOD: 1 LAV FEE board 32 channels (1 dead), 64 channels in the TEL62 (1/2 TDCB) Status:  4 LAV FEE boards are provided by LAV people  Threshold offsets for 4 LAV FEE boards to be measured in September  The 5 th LAV FEE board will be provided by LAV people  Cabling (patch panel to LAV FEE, LAV FEE to TEL62) to be done in September, all cables ready 6

V.Duk, INFN Perugia FE DCS (standalone mode) LAV FEE Linux PC (control room) Linux PC (ECN3) USB interface Ethernet, SSH LAV FEE Status:  The same PC will be used for HV and FE DCS  USB interface to be bought in September  Software will be provided by LAV people 7

V.Duk, INFN Perugia DAQ CHOD+NHOD: Standard Wiener crate 1 TEL62, 3 TDCBs (2 equipped by CHOD and ½ by NHOD) 8 Status:  Ingredients ready  Mounting in September

V.Duk, INFN Perugia CHOD L0 trigger 9 Hardware trigger ( σ ~ 2-3 ns) : Q1 can be implemented using LAV FEE ORs and NIM modules NHOD trigger: in the same way Firmware trigger ( σ ~ 0.5 ns) : CHOD firmware is based on the RICH firmware (input sorting, clustering) Impact point correction added (algorithm developed by Cristiano Santoni) L0 trigger primitive types and codes presented by Mauro Piccini in April Status:  Hardware trigger to be done in September (straightforward)  Firmware tests in progress (C. Santoni, Luigi Marzocchella)

V.Duk, INFN Perugia software 10 Status:  CHOD/NHOD reconstruction ready  CHOD/NHOD monitor to be implemented in September  New CHOD can be easily added

V.Duk, INFN Perugia Message for the New CHOD 11 itemPossible help from old CHOD HV HV DCSAccess to Linux PC FEPlace(s) in the 9U Wiener crate FE DCSAccess to Linux PC DAQ64 channels available, but one should think about cables from FE to TDCB SoftwareTR reconstruction available and can be modified We (Perugia group) can help but we need the detailed information as soon as possible
