MUSTANG2: An Advanced 90 GHz Camera for the GBT

这是一个进一步发展MUSTANG毫米波照相机的计划，该照相机已被开发用于NSF的绿色银行望远镜（GBT）。 主要的科学目标是通过Sunyaev-Zeldovich效应（SZE）获得星系团的深度，高分辨率观测，当光子穿过星系团并从高温星系团内气体散射并离开视线时，宇宙微波背景强度会减弱。 这项工作的更广泛影响包括对本科生和研究生进行仪器开发方面的培训。 该团队的成员积极参与费城地区的公共宣传活动，包括星星派对、费城科学节和对表现不佳的学校的指导。此次升级被称为MUSTANG-2，探测器的数量将从32个增加到223个。 探测器的灵敏度也将大大提高。 利用100米绿色银行望远镜在90 GHz的星系团中绘制SZE地图，将提供前所未有的绘图速度，分辨率和天空覆盖范围的组合，这将释放这些复杂物体的全部潜力。

This is a program for further development of the MUSTANG millimeter-wave camera which has been developed for use on NSF's Green Bank Telescope (GBT). The main science goal is to obtain deep, high-resolution observations of galaxy clusters via the Sunyaev-Zeldovich effect (SZE), a decrement in the cosmic microwave background strength as photons pass through a cluster and scatter off of the high temperature intra-cluster gas and out of the line of sight. Broader impacts of the work include the training of undergraduate and graduate students in instrumentation development. Members of the team are actively involved with public outreach in the Philadelphia area including star parties, the Philadelphia science festival and mentoring in low-performing schools.The upgrade is called MUSTANG-2, and will increase the number of detectors from 32 to 223. The sensitivity of the detectors will be greatly enhanced as well. Maps of the SZE in galaxy clusters at 90 GHz with the 100-meter Green Bank Telescope will provide a combination of unprecedented mapping speed, resolution, and sky coverage which will unlock the full potential of these complex objects.
