Background

• 2012 Starts the Scintilla project• Early version of trolley for dinamic tests• 2013 Build the test laboratory• 2013-2014 dinamic test of Simmetrica

detectors• 2015 Construct static irradiators

Test Laboratory

• Hardware• Software• Wherewithals• Human resources

Test equipmentsDinamic test trolley:• 11m movement length • Sample height 0.2 m to 2 m• Velocity max 2.2 m/s• Programmable parameters• Connection to the central server, remote controlled

TestControlled/checked environmental parameters:•Background radiation•Temperature•Air pressure•Humidity

Static irradiators

For gamma sources:

•Led shielding 25 cm thick~100 millions ofattenuation for 1 MeV peak

•Remote controlled•Sample size max.

D=5.5cm H=6.5cm

For neutron sources:•Polyethylen shielding

30 cm thick•Remote controlled

Source movement:

• Electromechanic• Full moving time 1.3 s• Unshielded 0.5 s• Acceleration 0.83 m/s2

• Velocity 0.5 m/s• Deceleration 5 m/s2

Control software

• Controls both system (static, dinamic) movements

• Setting up test parameters• Collects and stores:

1. Detector responses2. Movement parameters

(position + time)3. Environmental data

• Report Under development
