LAMBDA — Large Area Medipix3-Based Detector Array

The Fluorescence detector Array of Single-pixel Telescopes (FAST) is a proposed large-area, next-generation experiment for the detection of ultra-high energy cosmic rays via the atmospheric fluorescence technique. The telescope’s large field-of-view (30 ×30) is imaged by four 200 mm photomultiplier-tubes at the focal plane of a segmented spherical mirror of 1.6 m diameter. Two prototypes are installed and taking data at the Black Rock Mesa site of the Telescope Array experiment in central Utah, USA. We present the process used for optimization of the optical performance of this compact and low-cost telescope, which is based on a simulation of the telescope’s optical point spread function.

Observational Test

Consider the possible astrometric use of the following concept: If the image of a field of stars is moved past a high-speed detector array at a precisely known velocity, relative positions can be determined by measuring time intervals. Attractive features of this approach are: times can be measured very accurately with photoelectric detectors; a relatively large area of the sky may be swept for reference stars; the images are measured essentially on-axis; and seeing effects can be partially frozen out. The only available detector with spatial and temporal resolution and stability adequate for this technique is the MAMA. A rudimentary observational test with this detector has yielded promising results. Further observations are planned to determine whether milliarcsecond accuracy can be obtained.
