PXIE MEBT吸波体样机的高功率密度试验
High power density test of PXIE MEBT absorber prototype
摘要：
费米实验室的PXIE计划的目标之一是证明从一个初始CW 162.5 MHz H-聚束训练出来的聚束形成任意聚束模式的能力。在2.1 MeV中能束流传输（MEBT）中，将通过将不需要的束流引导到吸收器上进行逐束流选择，该吸收器需要承受高达21 kW的束流功率，聚焦到具有约2 mm rms半径的光斑上。用钼合金TZM制造了两个吸收体原型，并用28 keV DC电子束进行测试，达到PXIE所需的峰值表面功率密度17 W/mm 2。测量温度和流动参数并与分析进行比较。本文介绍了吸收器原型和关键的测试结果。
英文摘要：
One of the goals of the PXIE program at Fermilab is to demonstrate the capability to form an arbitrary bunch pattern from an initially CW 162.5 MHz H- bunch train coming out of an RFQ. The bunch-by-bunch selection will take place in the 2.1 MeV Medium Energy Beam Transport (MEBT) by directing the undesired bunches onto an absorber that needs to withstand a beam power of up to 21 kW, focused onto a spot with a ~2 mm rms radius. Two prototypes of the absorber were manufactured from molybdenum alloy TZM and tested with a 28 keV DC electron beam up to the peak surface power density required for PXIE, 17W/mm2. Temperatures and flow parameters were measured and compared to analysis. This paper describes the absorber prototypes and key testing results.
