From: Bob Webber [webber@fnal.gov] Sent: Friday, October 20, 2006 9:04 AM To: 'PD-Meson-planning@fnal.gov' Subject: Oct 10 2006 HINS Meeting Minutes Jim Volk - - Filled us in on status of Batavia Wilson St. bridge project. They hope to begin work in March 2007. Steve Hays - - Has already provided Henryk et al. with power supply (voltage source) that is expected to work as long-pulse ion source arc modulator supply. - Will have ready next week, two 4-quadrant analog control power supplies (+-10mA control for +-100A) use in ATF 1.3 GHz phase shifter system - Expects DSP feedback system available for 2-quadrant supplies in a few weeks. These supplies will be controlled by high speed serial link input signal. Bob Webber - - Discussion of waveguide coupler layout that Steve has created. The coupler and appendages are much larger in overall size than had been imagined. Will obstruct access to upper cable tray along E-W waveguide run. - Discussion of water pipes and 3 1/2" coax entry into cavity test cave. Moretti, Ball, and Wesseln are to determine location/plan for these by next week. What does cross-section of entry of pipes and coaxes into cave look like? Al Moretti - - Waveguide coupler and appendages are expected to arrive today! - Will pull out of storage lengths of 3 1/2" coax so that Wesseln can design layout from waveguide coupler to end points in cavity test cave. Piekarz/Schmitt - Will test short pulse (old style) arc modulator in MS6 today. Hope to run pulsed 50KeV beam next Tuesday. When that is stable, they will try longer pulse with Hays' power supply. - Moehs has made progress toward long beam pulses on the ion source test stand, approaching 40mA for nearly 1msec, presumably at low repetition rate Chris Jensen - - Modulator internal water plumbing work to be completed probably today; only minor other items remain - Plans to hipot late next week - Oil fill of pulse transformer and klystron has been delayed due to techs fixing Tevatron - Klystron/modulator interlock rack is now in Meson and being powered (includes McDowell PLC). Should be live signals available to control system within days, water flows, etc. - Discussion with Jim Steimel on cable label convention; they need to include McDowell in these discussions - Agreed that connection between cable label convention and control system device names will be weak at best, likely cables end up with two labels... - Reminder that Toshiba should be give a couple week's 'heads-up' before we plan to operate klystron Controls - - Dennis Nicklaus has two PCs for consoles now in Meson. Sharon Lackey will help us understand situation with required access accounts. - Peter Lucas reports that Kucera will have HRM installed in Meson next week. Lucas also will help us understand timing aspects of HRM data acquistion system. - Webber requested that all analog I/O channels of this HRM be put into the database, at least with temporary names, as the HRM is installed so that the channels are usable without having to create new db entry whenever a channel is first used. - Discussion on how McDowell PLC communicates with control system/IOC controller? Sharon Lackey will pursue this and report next time. Jim Steimel - - Steimel and Moretti need to develop list of RF signals that will be brought to RF racks for controls, RF equipment interlock, and monitoring purposes. - Reports problem with waveguide shutter operation under control of safety system switches. Steimel will work with Federwitz to resolve. - Expects to install RF rack top entry panel, RF gate card, and NIM crate tomorrow. - Continues to work on safety documents. Mike Andrews - - Overseeing MS6 ion source operations of Piekarz and Schmitt. - Reports that Meson roofing work will not be completed this season, maybe only 3-4 flutes power washed and re-sealed before winter sets in. Plan to meet again next week. Bob Webber mailto:webber@fnal.gov phone (630)840-5415 pager (630)722-0085
