This equipment grant application requests a Canadian contribution to a critical upgrade of the voltage control system for the Penning trap at the heart of ALPHA apparatus. This upgrade is a joint capital project that is being undertaken by the entire ALPHA collaboration. The upgrade is motivated by our recent experimental demonstration of evaporative cooling of antiprotons down to 10 K; this experimental technique has been a workhorse in the field of Bose-Einstein Condensation but has almost never been used with charged plasmas. In the process of achieving this very-important milestone, it has become apparent that electronic noise and the resolution of our Penning trap voltage control system are now the limiting factors for base temperature and cooling efficiency. The upgrade to the control system requested in this application will overcome these limitations, and represents the most promising route to anti-hydrogen trapping and spectroscopy. Moreover, the requested equipment is critical to achieving the goals of our SAP Project Grant, and directly support an integrated and extensive HQP training initiative.

这项设备拨款申请要求加拿大为阿尔法仪器核心的彭宁疏水器的电压控制系统的关键升级提供捐助。这次升级是一个联合资本项目，由整个阿尔法合作公司承担。这一升级是因为我们最近的实验演示了反质子蒸发冷却到10K；这项实验技术一直是玻色-爱因斯坦凝聚领域的主力，但几乎从未用于带电等离子体。在实现这一非常重要的里程碑的过程中，很明显，电子噪声和彭宁陷阱电压控制系统的分辨率现在是基础温度和冷却效率的限制因素。本申请中要求的控制系统升级将克服这些限制，并代表了反氢捕获和光谱分析的最有前途的途径。此外，所需设备对实现我们SAP项目赠款的目标至关重要，并直接支持综合和广泛的HQP培训计划。
