A STARChina collaboration has been established (Six Institutions from China) ? University of Science and Technology of China, Hefei (USTC) ? Tsinghua University ? Shanghai Institute of Applied Physics (SINAP) ? Central China Normal University, Wuhan (CCNU) ? Institute of Modern Physics, Lanzhou (IMP) ? Institute of High Energy Physics, Beijing (IHEP) ? Chinese collaborators are playing a major role in physics analyses involving open charm, Cronin effect, and elliptic flow as part of STAR’s focus on studies of a new state of matter (the quarkgluon plasma) at RHIC ? Chinese groups are leading in prototyping and development for a largearea MRPC timeofflight detector for STAR. ? This is the first major USChina collaboration on high energy nuclear physics and we have had a very successful beginning. ? The STARChina TimeofFlight Construction Project has been covered under the USPRC HEP Agreement since 2023 to ensure smooth construction of the TOF detector and operation of the STARChina collaboration. 2023/6/2829 第 59屆東方論壇，上海 Major Milestones of STARChina TOF Project ? CCNU and IHEP joined STAR collaboration in 1999 for TOFp。 SINAP, USTC, Tsinghua and IMP joined STAR collaboration in Oct. 2023. ? USTC team began MRPC RD in Aug. 2023 with the supports of NSFC, STAR and other Chinese collaboration institutions. ? Joined in US/PRC Cooperative Agreement on High Energy Physics since 2023 (22nd Meeting) ? Prototype MRPC (multigap resistive plate) timeofflight detectors, produced jointly between USTC and Rice Univ. and operated successfully in STAR (20233 and 20234 RHIC runs). Physics results on identified particle spectra and on semileptonic charm decays have been published. ? Approval of RHICSTAR Physics and the Construction of Barrel STARTOF” by the National Natural Science Foundation of China (Sept 10, 2023, Budget: USD) ? Approval of the STAR TOF upgrade proposal by BNL Technical Advisory Committee and Submission of the Proposal to DOE (July 2023) ? Technical Review of proposal by DOE, planned Aug. 2023 ? Suppose DOE approval in Oct. 2023, full construction start October 2023 2023/6/2829 第 59屆東方論壇，上海 MRPC TOF Barrel RD ? RUN 20233: TOF installed in STAR ? 24 MRPC modules produced at University of Science Technology China ? 6channel frontend cards, with amplifiers and discriminators, CAMAC readout ? Run 20234: TOF installed in STAR ? 5 new modules from USTC and 5 from Tsinghua University, Tsinghua developed automated techniques for manufacturing ? 24channel frontend cards with amplifier and discriminator ? RUN 20235, TOF installed in STAR, ? 16 new modules from Tsinghua ? First time use of full onboard readout electronics: digitization of data onboard ? First use of ALICE PCIPC based DAQ 2023 2023 G. Eppley et al. 2023/6/2829 第 59屆東方論壇，上海 Completed Prototype 28 module MRPC TOF Tray installed in STAR Oct. ‘ 02 in place of existing central trigger barrel tray Neighbor CTB Tray EMC Rails FEE MRPC design developed at CERN, built in USTC/China Prototype Tray Construction
