  1. Department of Nuclear Medicine Design goal :-Increased Yield By 50%. -Low and quick maintenance cycle. -Suitable to Multi-geometrical internal volume Chamber. -Stand alone uPLC- PC GUI. -Low cost High reliability.Future Projects:-New valves layout for less radiation damage.-One isolation foil used in grid flange, Water cooled, no helium. Improvement of the 11C gas target Erol Bars, Munawwar Sajjad , Mike Haka, Steve Toorongian

  2. 11C Target Properties: Internal gas Volume:188cc Length internal Chamber: 8.5” Orifice in: 0.472” Orifice OUT: 2” Water Flow: 6-8Lm 2X2way GE valves used (COLD CUBE control - Cole Parmer) 1 kulite Pressure sensor All Aluminum parts 6061 Isolation Foils: 25um Al (Tron Side) 0.5mm Al 2024(0.02”) (Trg) Target face O-ring :Viton Helium flow: 50L/min. Energy: 22.5Mev Beam Current: 35-40uA 11C in Maintenance condition Previous Target

  3. 11C Design concept

  4. Target 11C (Nemo) Software uPLC Pic microcontroler: PIC16F876:22I/O,5AN,Ser,PWM, 8K x 14 words Flash,20MHZ…. Software: PicBasic Pro Compiler MicroCode Studio ,MPLAB Chip burner: PicStart+ -Visual basic 6.0 used as GUI - Communication protocol serial. -Stand alone platform (File.exe)

  5. 11C Yield Gas used 1%Oxygen+Nitrogen Average data graph over 100 runs Results

  6. Future Projects. 11C Target #2 New Layout Water Cool Grid Foil flange (one foil used) 500W power analysis. Grid Face 491K Conclusion: Projects has shown all the design goals. Cosmosflowork
