Repeater(REBO)

Repeater(REBO). The first design comes from Vienna Very simple and smart No regulator on MAMBO( No MAMBO design yet.) So many opt couplers(20). But Vienna said it is necessary for I2C protocol. No monitor other than HV current Configuration 1 DOCK contains 6 REBO

Presentation Transcript

  1. Repeater(REBO) • The first design comes from Vienna • Very simple and smart • No regulator on MAMBO( No MAMBO design yet.) • So many opt couplers(20). But Vienna said it is necessary for I2C protocol. • No monitor other than HV current • Configuration • 1 DOCK contains 6 REBO • 1 REBO connects 4 hybrids (16 APVs) • (We need 18 hybrids readout/DOCK) • Connector/Cable choice • NANONICS conn. on hybrid. • Connector on REBO (not on MAMBO)

  2. IHV monitor Conn. MAMBO/FADC Clk/Trg Conn. Hybrid Analog out APV control

  3. HV current monitor DCU25F developed for LHC Low speed ADC for monitroing I2C protocol same as APV25

  4. CLK/TRG CLK in Global Floated DELAY25 developed for LHC Match Clk phase and level I2C protocol same as APV25

  5. Analog output 22nF capacitor Global Floated

  6. Hybrid • Cooling problem(thermal connection TPG and AlN block) Change hole shape?

  7. FLEX • Put cover layer • To avoid shorts due to abnormal Au deposition. • Delivered • Thick Au (0.35um) succeeded • No shorts • The accuracy of cover layer cutting is poor.

  8. Problem on SVD2.1 FLEX Gold Bridging (short) from upper flex to traces below

  9. Assemble • We have all ladder components( bridge, rib..) • Assembling procedure • Assemble half ladder (DSSD, Hybrid, FLEX) • Wire bonding • Test (w/ APVDAQ? Need connector for nanonics flat cable) • Assemble full ladder (bridge, rib) • Where? • Princeton? • Hybrid production. APVDAQ. • Less man power? • Melbourne? • send Jig from KEK? • In Japan? • How to make bonding? RIKEN, HPK…

  10. Plan Princeton or/and Melbourne All ladder assemble work KEK Plan A Send all parts Melbourne/HPK/RIKEN KEK KEK Half ladder Assemble DSSD+FLEX+Hybrid Wire bonding Full ladder Assemble Test Plan B RIKEN bonding machine are in REPIC company (Chiba) We can use it until August 2007.
