【摘要】 本文详细介绍了用于神光Ⅱ装置八路功率平衡的全自动精密小能量测量系统,并用自动控制半波片衰减装置对其性能进行了测定。系统稳定性精度优于1%(Rms),在线调试量程可达三个以上量级范围。
【Abstract】 A full-automatic precision energy measurement system on small signal was described in detail, which was used for eight beams’ power balance in SHENGUANG II. An assembly attenuator of half-wave plate and polarizers is used to check up the performance of the system. The precision of stability precedes 1% (rms). And the measuring range is more than three magnitudes.
