Dear all find the change request concerning the IR region attached. This has already been discussed in the most recent SiD Newsletter As Karsten said, feel free to read this and send comments. For the sake of simplicity and to avoid duplications, I'd suggest, that Andy and myself will collect comments from SiD, compile them together and send them to Karsten. Cheers and see hopefully many of you in Belgrade Marcel -------- Forwarded Message -------- Dear SiD and ILD spokepersons, dear Mike and Hitoshi, here is a draft of the change request for the ILC interaction region configuration. We propose to change the TDR design to an underground area that can be accessed via a large 18m shaft for the detector installations. I plan to finalise this change request document at a dedicated joint MDI/CFS session that takes place on Tuesday, October 7th, at 09:00 at the coming LCWS in Belgrade. The content of this request and the document itself has been discussed within the MDI and CFS groups and found agreement between all involved parties. I would like to ask you to discuss this draft document especially in the detector concept groups and come back to me with comments well before the Belgrade workshop. I plan to submit the change request soon after the discussion session at LCWS. Thanks and cheers, Karsten. ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the SID-ALL list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=SID-ALL&A=1
