The Compact Pulsed Hadron Source (CPHS) has launched at Tsinghua University to develop a neutron source based on a 13-MeV, 50-mA proton linac, consisting of an ECR ion source, LEBT, RFQ, and DTL. The primary design of the DTL for the CPHS is presented in this paper, which includes the dynamics calculation, RF field optimization, and error analysis [...]

Stochastic cooling of the Spectrometer Ring (SRing) at the High Intensity heavy-ion Accelerator Facility (HIAF) project in China, which is used mainly for experiments with radioactive fragment beams, is applied to speed up the cooling process of a stored ion beam. In this study, both a Faltin traveling wave structure and a novel slot-ring standing wave structure based on a ceramic vacuum chamber are discussed and evaluated for the pickup/kicker of the SRing stochastic cooling system.

Research on Drift Tube Linac Model Cavity for CPHS
/ Zheng, S X (Beijing U. of Tech.) ; Guan, X (Beijing U. of Tech.) ; Wei, J (Beijing U. of Tech.) ; Zhang, H Y (Beijing U. of Tech.) ; Billen, J H (TechSource, Santa Fe) ; Young, L M (TechSource, Santa Fe) ; He, Y (NUCTECH, Beijing) ; Li, J (NUCTECH, Beijing) ; Zhang, D S (NUCTECH, Beijing) ; Li, J H (Beijing, Inst. Atomic Energy) et al.
The CPHS project in Tsinghua University plans to construct a 13 MeV linear accelerator to deliver a pulsed proton beam having an average beam current of 2.5 mA. A Drift Tube Linac (DTL), following a Radio Frequency Quadrupole accelerator(RFQ), will accelerate protons from 3 to 13MeV. [...]

For a bunched beam, the signals on pickups are coherent, providing a signal power proportional to the square of the number of particles. For a coasting beam the individual particle signals have a random phase; therefore, the overall signal is proportional to the particle number N. [...]

A diagonal-cut type beam position monitor (BPM) has been developed for the High Intensity Heavy-Ion Accelerator Facility (HIAF) project at the Institute of Modern Physics. Compared with other types of BPMs, the diagonal-cut type BPM has almost perfect position linearity, i.e., no non-linear correction required, which is advantageous for beams that are transversally large and have a complex charge distribution.

Prompt and delayed γ-ray spectroscopy of the neutron-deficient, semi-magic isotope 187Pb has been performed using the recoil-decay and isomer-decay tagging techniques at the Argonne Gas-Filled Analyzer. A new 5.15(15)-μs isomeric state at only 308 keV above the spherical 3/2− ground state is identified and classified as a shape isomer. [...]
