Date: Tue, 1 Jul 2008 16:07:13 +0200 From: Leif Joensson Dear Lucie, I would like to inform you that we send in the second prototype of the FEC for mounting of the components tomorrow (Wednesday 2.6.2008). We have had two boards made and in a previous meeting with Luciano we agreed that one of them should have the so called 25 MHz ALTRO chips, which we received recently from CERN, whereas the other one should have the 40 MHz ALTRO's. Although promised by CERN a long time ago, we have not yet received these chips. We have decided to have the boards completely equipped except for the 40 MHz chips on one of them. When we get the boards back we will send the one, which should contain the 40 MHZ chips to CERN for mounting. I could also inform you that we have received the 25 MHz ALTRO chips from Takeshi. I have not yet got any information about the status of the test report which was promised until middle of June (see mail from you below) which I guess have to be evaluated before the order of the remaining preamp chips is made. We have also not got the RCU firmware which is needed to run at sampling rates higher than 10 MHz and which should be ready on the 6th of June (see mail below). We are also waiting for information on the reference voltages for the ALTRO. Best regards, Leif Dear Leif, I discussed the list of deliverables requested from CERN with Luciano Musa. We came to the following best-effort deadlines at which he can provide them: 1: The test report of the preamplifiers (results from Luciano, Takahiro, Matti) => middle of June 2: Send the preamplifier chips to Lund => shipment will be prepared by Antoine Junique over the coming ~1 week 3: Send ALTRO chips to Lund for second prototype => shipment will be prepared by Antoine Junique over the coming ~1 week 4: Provide information on reference Voltages for the ALTRO => no later than June 6th 5: RCU firmware modifications required to go from 10 MHz to 40 MHz => this item is also needed for ALICE and will be ready approx. June 6th In parallel, we suggest that you also get in contact with Takeshi asking him to send the 435 ALTRO chips, that CERN sent to Japan some time ago, back to Europe. We seem to remember that he agreed to send them to Lund. With our best regards, Luciano and Lucie
