 ==== ASICs configuration ====
+The initial configuration with both the return chamber calibrated (TDC_RETNEW_8) and  the 4 FEBs of the coaxial chamber is **TDC_RETNEW_9**
+Two runs were use to calibrate those Febs to 480 VTHTIME: 741263 and 741278
+Nevertheless the HV was set to 7800 V when it was done and detector noise pollutes those runs.
+The new state to be used for cosmic data taking is **TDC_RETNEW_12**
+at 1 kV on all chambers we got run 741284

+{{ :cern_july18:run741284_allstrip7.png |}}
+{{ :cern_july18:run741284_allstrip8.png |}}
+The return strip chamber is a bit noisy (ground connection to be adjusted) and **the minimal threshold is 504** ( ~ 65 fC)

+The current environnment  is
+<code>
+acqilc@lyosdhcal11:~$ slccontrol --slc-ptstatus
+          P          T
+.00     295.45
+acqilc@lyosdhcal11:~$ slccontrol --slc-humstatus

+.53     294.71      37.14     294.89
+</code>
+The start of the acquisition can be done with the //restart_daq// script
+<code>
+#!/bin/bash
+shopt -s expand_aliases
+. ${HOME}/.daqrc
+daqcontrol --jc-kill
+sleep 2
+daqcontrol --jc-start
+sleep 2
+slccontrol --slc-cre;slccontrol --slc-init;slccontrol --slc-conf
+sleep 1
+slccontrol --slc-lvon
+daqcontrol --daq-create
+daqcontrol --daq-discover
+daqcontrol --daq-service
+daqcontrol --daq-initialise
+daqcontrol --daq-download --dbstate=TDC_RETNEW_12
+daqcontrol --daq-setvth --vth=504
+daqcontrol --daq-configure
+daqcontrol --trig-spillof --clock=1000

+#curl -g http://lyosdhcal10:45000/FDAQ/CMD?name=SETTDCMODE\&VALUE=1
+</code>
+Then a run is started on lyosdhcal11 with
+''daqcontrol --daq-start;daqcontrol --trig-resume''
+and  stopped with
+''daqcontrol --daq-stop''
+The last line of //restart_daq// is commented. If one wants to run in trigger mode (only acquisition frame with trigger in are transmitted):
+'' curl -g http://lyosdhcal11:45000/FDAQ/CMD?name=SETTDCMODE\&VALUE=1 ''
+and go back in normal mode with
+'' curl -g http://lyosdhcal11:45000/FDAQ/CMD?name=SETTDCMODE\&VALUE=0 ''
