- Sergey: may be able to start cosmic run with CDC and FDC over the weekend.

- Nacer made presentation about dE/dx optimizing the pion/proton separation from rho photoproduction.  
  
- FDC threshold upgrade is done: all modules, cables installed; Hovanes finished the control system. Has to be tested, best with DAQ and software trigger looking at the noise.

- There WAS a problem with one FDC LV module - several channels didn't regulate the voltage. Module was replaced and now is OK.

- Naomi still can't get the self-triggering working; P2 triggering is only working sporadically; suspects any and all of the modules in the VXS crate. In any case the target has been installed and most likely will not be possible to place iron source inside the CDC before the end of the run.

- TRD status: the entrance window of the TRD prototype has been replaced by a chromium one (much less material) by Brian Kross. The detector has been installed in the Hall, as well as a new VXS crate that will be used as an independent DAQ for the TRD tests.
 
 
- Nacer nearly missed the meeting (confusion with the summer saving time), wanted to present his dE/dx studies. He will do it next meeting (it two weeks).
