Tile Calorimeter: Radiation Tests

Level 1 adder boards

• TID tests:
 
SRL= 1.22 Gy/10y
 
• Test 1 (1999): 2 boards irradiated
• total dose applied: 536 Gy
• no problems observed
RTC= 1.22 * 3.5 * 5 * 4 = 85.4 Gy
 

• NIEL tests:
 
SRL= 1.4 * 10**11  n/cm**2/10y
 
• Test 1 (1999): 2 boards irradiated
• total fluence applied: 2 * 10**13 u
• no problems observed


RTC= 1.4 * 10**11 * 5 * 1 * 4 = 2.8 * 10**12 u
