The new international accelerator facility for antiproton and ion research (FAIR) at GSI in Darmstadt, Germany, is one of the largest research projects worldwide and will provide an antiproton production rate of 7 × 10(10) cooled pbars per hour. This is equivalent to a primary proton beam current of 2 × 10(16) protons per hour. For this request a high intensity proton linac (p-linac) will be built with an operating rf-frequency of 325 MHz to accelerate a 35 mA proton beam at 70 MeV, using conducting crossed-bar H-cavities. The repetition rate is 4 Hz with beam pulse length of 36 μs. The microwave ion source and low energy beam transport developed within a joint French-German collaboration GSI/CEA-SACLAY will serve as an injector of the compact proton linac. The 2.45 GHz ion source allows high brightness ion beams at an energy of 95 keV and will deliver a proton beam current of 100 mA at the entrance of the radio frequency quadrupole (RFQ) within an acceptance of 0.3π mm mrad (norm., rms).
位于德国达姆施塔特GSI的新的反质子与离子研究国际加速器设施（FAIR）是全球最大的研究项目之一，每小时将提供7×10¹⁰个冷却反质子的生产率。这相当于每小时2×10¹⁶个质子的初级质子束流。为满足这一需求，将建造一台工作射频频率为325 MHz的高强度质子直线加速器（质子直线加速器），使用导电交叉杆H型腔体来加速能量为70 MeV的35 mA质子束。重复频率为4 Hz，束脉冲长度为36 μs。在法国 - 德国GSI/CEA - SACLAY联合合作项目中开发的微波离子源和低能束流传输装置将作为紧凑型质子直线加速器的注入器。2.45 GHz离子源可产生能量为95 keV的高亮度离子束，并将在接受度为0.3π mm mrad（标准，均方根）的情况下，在射频四极杆（RFQ）入口处提供100 mA的质子束流。
