  2. Overview • Signal Integrator • DAQ cards • VME system • Future Work

  3. Signal Integrator • A card has been developed to integrate the signals from the PMT and photodiodes • Integrates using RC network based around a fast op-amp. • Uses an ‘integrate’ signal from the Trigger Fanout or a DIO card and is read out by an ADC card in the PC • At DESY (Feb ’05) we failed to get it to work – operator fault! It’s been tested again at RHUL (using ADC and DIO signals as at DESY) and works as expected Integrator card signals

  4. DAQ Cards • All of the data acquisition is timed from the LaserTrig II card. This signal is delayed and fanned-out using both TrigFan I and counters on the DAQ cards. • A new DAQ card (PCI –based) is being investigated in order to reduce the amount of inter-card communication

  5. VME System • A new VME sub-rack and master processor (running Linux) is currently being setup and tested • The whole DAQ will move into this VME sub-rack including ADC/DAC cards as well as the existing LaserTrig II, integrator cards etc • LabVIEW will run under Linux, but it is envisaged the ‘final’ DAQ software will be in C/C++

  6. Future Work • The new laser at PETRA: the current LaserTrig II card could drive the Surelite Continuum laser, with only minimal changes to the cards’ output drivers • Integration of control and acquisition on to the new VME system – this will include purchase of a 100 or 200MS/s multi-channel ADC card. • Continuing work on the DAQ system – remaining with Labview at the present but will migrate to C/C++ later
