The vacuum system of the beam-line is mainly made up of the vacuum chambers, vacuum pipes, bellows, ion pumps and valves etc. After the upgrade, most of the old vacuum devices will be reused except that a few is new. These old vacuum devices consist of 21 chambers, 22 pipes, 21 bellows, 31 ion pumps and 28 valves. The total surface area cf the old vacuum chambers and pipes is about 1.2×10-6 cm2. They were contaminated by oil vapor seriously, so, the vacuum cleaning展开更多

At the same time, the positions or contents of the experimental terminal have been changed and a new curing cancer beam line has been built up. The length of the HIRFL post-beam line vacuum system has been added up to 128 m from previous 108 m. It is required that the system vacuum degree must not be lower than 1×10^-5 Pa after upgraded. Fig.1 3hows a part of the upgrading HIRFL post-beam line vacuum system.展开更多
The quadrupoles in the HIRFL experimental Hall were re-measured last year for upgrading of HIRFL. All quadrupoles's type and parameters are listed in Table 1.

Recently, the main RF parameters of the cavity were measured without power, the tuning driving control system and fine tuning system were adjusted and worked well, the full power test on the 50Ω dummy load on amplifier was finished and successful in the manufactory in Shanghai and Nanjing.All of the equipment of the new rebuncher (including RF resonator and tuning driving system, 40 kW amplifier and so on) were delivered and installed on the beam line in SSC hall in HIRFL at IMP last summer.展开更多

It is made up from vacuum chambers and pumps and some equipment for vacuum measuring and beam detecting. This system's surface area is 8 ×104 cm2 and the bulk is 110 1. It is required that this system's vacuum degree must be lower than 1×10-6 Pa. To get this target, we cleaned the vacuum chambers in our Ultrasonic Cleaning Station and then展开更多
