  1. Linac4 Instrumentation DayFaraday Cups • In order to measure the beam intensity three Faraday Cups will be installed in different places • LEBT • Low energy • Spectrometer • Low energy • Moving Diagnostics Bench for the three DTL tanks • High energy C. Bal AB/BI/ML

  2. Faraday CupsScheme of Linac4 C. Bal AB/BI/ML

  3. Faraday CupsSpecifications LEBT • Low Energy: 95 keV • Commissioning & Operation • Retractable • Acceptance FC ø80 mm • Acceptance Tank ø100 mm C. Bal AB/BI/ML

  4. Faraday CupsMechanical Design LEBT C. Bal AB/BI/ML

  5. Faraday CupsMechanical Design LEBT • Bias Ring, Collector and Housing made of St. Steel • Vespel Insulators for electrical isolation • Conical Collector • Use of metal seals only • Flanged High Voltage Feedthrough • Flanged Signal Feedthrough • Linear Pneumatic Drive (travel 102mm) • Flange DN150CF (øouter 202mm) • Parts slide into Housing and will be closed by dismountable Face and Back Plate C. Bal AB/BI/ML

  6. Faraday CupsSpecifications Spectrometer • Low Energy: 95 keV • Temporary installation • Commissioning only • Fixed • Similar design as for LEBT C. Bal AB/BI/ML

  7. Faraday CupsSpecifications Moving Bench DTL • High Energy: 40 MeV • Commissioning only • Retractable • Requires Cooling • Requires Energy Absorber (levels to be defined) • Design under development C. Bal AB/BI/ML

  8. Faraday CupsElectronics • Local read-out by means of a scope • Remote controlled at a later stadium C. Bal AB/BI/ML
