Updates - RFQ/LEBT – RFQ energy issue continues – Additional energy measurements are being planned – Waiting for vendor to analyze alignment data of RFQ rods – Redone measurements of Einzel Lens – will make some changes and re-measure – Re-measuring field flatness of RFQ Budget News – No news yet – PO’s are being looked at/slowed down on second floor Long Shutdown just 6 weeks away! – Lots of PIP related studies underway Work continues on RLS/Tracking of effort – Elmie still completing tables A short Booster kicker has been potted – ready to start on another

Booster Absorber Review Complete Introduction: The current notching scheme in the Booster will not be adequate for the future 15 Hz operation due to high radiation losses. A new notching scheme has been proposed using 3 long kickers located at Long 12 that kick the beam horizontally into a new absorber at Long 13. We were asked to review the design and feasibility of the new notching system and comment on potential improvements. Recommendations – Kickers: Use the bunch by bunch transverse damper diagnostics to map the notching kicker waveform. – Absorber: 1. Consider solutions for additional shielding on the wall side of the absorber that do not include sand bags. A direct comparison of the proposed additional steel vs. a comparable amount of concrete should be examined. At this point we may expect that the prompt radiation is dominated by moderate energy neutrons. To make a more complete containment inside the tunnel, one could fabricate shielding blocks special-made for this location. Vendors which make concrete shaped to specification are available locally. Consideration for 'heavy' concrete vs. the standard mix would be based on MARS simulations. Mokhov has a contact name at Argonne who regularly obtains specially shaped heavy concrete shielding. 2.Consider aisle side alternative designs that include marble.
