  1. Readiness for scintillation blocks characterisation at Prague Vít Vorobel

  2. Area Scheme

  3. Radio-contamination prevention • Clean room personal protective equipment (coat, cap, facecloth, gloves, shoes) • Dust, temperature and humidity monitor. • Sticky pad at the entrance.

  4. Radio-contamination prevention • Air Conditioning Unit, DAIKIN, Split FTXR-EV1B • Control of temperature and humidity. • Dust filtering. • Laminar Flow Box, Heraguard HPH 12/95 • HEPA filters H14, efficiency >99.999% for particles 0.3 mm. • Horizontal air flow. • We are getting an experience with dust. • Present level: • Flow-Box OFF →10^6-10^7 particles 0.5 μm / m^3 • Flow-Box ON → 10^3-10^4 particles 0.5 μm / m^3 • Manipulations with naked blocks to be done inside the Laminar Flow Box.

  5. Electron Source • Monoenergetic electron source - “Spectrometer” • Power SuplyTTi, PC controlled. • 2 magnet yokes (for 2 spectrometers), low hysteresis material. • 90Sr, 370MBq • Coil, shielding…tiny components expected form Dubna in 1 month, transport permitting needed. • Spectrometer calibration • Si(Li) detector, 3 mm thickness, 20 mm2. • Si(Li) 5 mm, 75 mm2. • 207Bi, 100 kBq. • XY-table • Range increased to 45 x 45 cm. • Velocity 38 cm/min. • Control with PC serial port.

  6. Measurement • Black Box 100 x 130 x 130 cm • enough space for XY-table, “spectrometer” and 4 X-wall blocks with PMTs. • PMTs • ≥4pieces of NEMO-3 5’ PMTs to be delivered from LSM in 2 weeks. • Delta E - Polystyren 300 μm, 2 PMTs in coincidence • Signal readout – Digitizer CAEN V1720, 8 channel

  7. Other material • Mylar – expected delivery next week • Mylar film 12µ 16,8g/m² métallisé Alu 1 face, width: 1185m • 1 roll of ~ 17-20kg 1000linear meter, MICEL Industrie • Teflon tape – Czech, French? • Optical contact – glycerol?

  8. Readiness for blocks characterisation at Prague • Red text is for missing items or actions. • Radio-contamination prevention • “Clean” Room 2.6 x 4.3 m, entry 2.6 x 1.2 m. • Dust, temperature and humidity monitor. • Clean room personal protective equipment (coat, cap, facecloth, gloves, shoes). • Sticky pad at the entrance. • Air Conditioning Unit, DAIKIN, Split FTXR-EV1B • Control of temperature and humidity. • Dust filtering. • Laminar Flow Box, Heraguard HPH 12/95 • HEPA filters H14, efficiency >99.999% for particles 0.3 mm. • Horizontal air flow. • We are getting an experience with dust. Present level: • Flow-Box OFF -> 10^6-10^7 particles >0.5mum • Flow-Box ON -> >10^4 particles >0.5mum • Manipulations with naked blocks to be done inside the Laminar Flow Box.

  9. Measurement • Black Box 100 x 130 x 130 cm • enough space for XY-table, “spectrometer” and 4 X-wall blocks with PMTs. • XY-table • PC control, range 45 x 45 cm. • PMTs • ≥4pieces of NEMO-3 5’ PMTs to be delivered from LSM in 2 weeks. • Signal readout – Digitizer CAEN V1720 • Monoenergetic electron source - “Spectrometer” • Power SuplyTTi, PC controlled. • 2 magnet cores (for 2 spectrometers), low hysteresis material. • 90Sr, 370MBq • Coil, shielding…tiny components expected form Dubna in 1 month, transport permitting needed. • Spectrometer calibration • Si(Li) detector, 3 mm thickness, 20 mm2. • 207Bi. • Other material • Mylar – expected delivery next week • Teflon tape – Czech, French? • Optical contact – glycerol?
