Source Calibration for CYGNO_04 CYGNO_04 Geometry v3 (25,55,0)cm (-25,55,0)cm Source Fe55 Energy 5.9 keV Activity 3.7 MBq
Source Calibration for CYGNO_04 (25,55,0)cm (-25,55,0)cm Source Fe55 Energy 5.9 keV Activity 3.7 MBq - 14 slits 62.5 mm apart each other; 4.5 x 14.5 mm2 and 40 mm deep (the whole clean copper layer) For the 55Fe, our task is to have: On the COPPER On the `PMMA - 2 windows (1 per half volume) - 80 x 402 mm2 windows This setup should allow 10 kHz of events (about 2 Hz/cm2) Therefore, the existing cad-acrylic-box and inner cu are removed. Next, to implement the proposed structure of Cu and PMMA to check the events rate.
Source Calibration for CYGNO_04 144 mm 98 mm PMMA Box of size 1190 mm , 1040 mm, 720 mm. Thickness of the PMMA is 20 mm 144 mm -2 windows (1 per half volume) - 80 x 402 mm2 The windows are placed 98 mm apart each other and 144 mm from both sides of the box
