The six species heavy ion beam was accumulated with the help of electron cooling in the main ring of Cooler Storage Ring of Heavy Ion Research Facility in Lanzhou(HIRFL-CSR), the ion beam accumulation dependence on the parameters of cooler was investigated experimentally. The 400MeV/u 12 C 6+ and 200MeV/u 129 Xe 54+ was stored and cooled in the experimental ring CSRe, the cooling force was measured in different condition.

Abstract-The neutron detector of HIRFL (Heavy IonResearch Facility at Lanzhou) has been designed for in-beam nuclear experiments, capable of measuring neutron energy and discriminating neutrons from gamma-rays. The read-out electronics, receiving charge signals from photomultipliers of the neutron detector, should be capable of acquiring data of three things including quantity of electric charge, time-to-flight and pulse fall time. For satisfying the physical requirements of high precision, high integration density and minimum cost, we have developed a waveform digitizing system that acquires all the required data in single read-out process. The waveform digitizing system is based on high-speed switched capacitor array (SCA) chip named DRS4 that allows sample an interested region of analog signal up to a rate of 5 GSPS. A 14-bit pipeline ADC and a FPGA are employed to digitize the charges stored in SCAs and deliver the waveform data to the host computer via PCI bus. The software completes fitting the waveform and calculates the required data. In this paper the detail of the electronics and algorithms of the waveform digitizing system is presented.

“…In this case, the losses are determined by other causes and account for 10 -5 -10 -6 of the total beam current. The electrostatic bends were used to good effect in the EC 35, EC 300, and LEIR electron coolers with the maximum electron energy of 35, 300, and 40 keV, respectively [7,8]. However, as the energy goes up, an increasingly higher electric field is required, which necessitates a significant increase in the voltage applied to the plates of the capacitor producing this field.…”

A high-efficiency collector for a high-voltage electron cooler

et al. 2013

A high perveance collector with a small secondary emission ratio has been designed for a high voltage electron cooler. The distinctive feature of this collector is the fact that it consists of the cooled collec tor itself, which receives the electron flow, and a Wien filter installed ahead of it, which substantially reduces the secondary electron flux emerging from the collector. The main advantage of this design is the combination of the small secondary emission ratio and the high perveance with the small size and ease in manufacturing and adjustment. The results of calculations and experimental investigations of the combined collector are presented, and its different operating modes are investigated. The minimum attained secondary emission ratio is 5 × 10 -6 . The methods for further reducing this ratio are proposed.
