Auxiliary Detectors

Yale LampShade Array (YLSA)

• YLSA is made up of ion implanted silicon strip detectors manufactured by micron semiconductor ltd. (UK)
• 5 detectors with 16 strips each, 80 energy + 80 time channels
• Using detectors with many strips on one wafer allows angles to be measured AND reduces the electronic noise of each channel
• YLSA subtends q=131°-166° and has a lab efficiency of 14%

Branching RAtio Detector at Yale (BRADY)

• BRADY consists of two 2 silicon detectors, each with 16 strips
• like YLSA, BRADY can be mounted within the scattering chamber
