	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. The RHIC transverse Stochastic Cooling Pickup uses a pair of high resolution 4-8 GHz frequency band planar loop arrays to measure the Schottky signals from the bunched beams in the two transverse planes of the two rings. Precision alignment between the two 381 mm long array boards was achieved by surveying two specially designed target fixtures outside the vacuum chamber and using a pair of high resolution, motor controlled, and force balanced actuators. Robust mechanical design was achieved by excluding wearable mechanical joints and fragile electronics inside the vacuum chamber. Both mechanical designs and structural analysis results, for the vacuum chamber and for the array board supports, are presented. Two horizontal and two vertical plane pickups have been fabricated and installed in RHIC for the FY2012 run. Successful performance has been reported.
