  7. KTeV target multiwire 7

  8. Standard vac box: Length (flange to flange) = 16 inches Height = 11 15/16” 6” coupling to beampipe and top for wire assembly Provision for 4” CF flange on bottom for ion pump UT: Length = 10 inches Mounted at 45 degrees Bayonet: Length = 6 1/4 inches Vac. Box: 14 X 14 3/16” Height (with motor)= 44 1/2” 6” coupling to beamline No provision for ion pump port KTeV: Length = 13.45 inches Dimensions 8

  9. Ceramic boards 9

  10. Ecool: steel frame with invar board Standard ceramic board Wire plane assemblies 10

  11. AuW wire - 25 m (NuMI and ecool), 75 m in beamlines Pitch: 125 m (wire wound at 250 m on both side of ceramic board and offset by 125 m), 250, 500 m BeCu wire - capability from 25 m to 600m as in old swics Ti strips - University of Texas multiwires use 5 m thick material, 0.2 mm wide. Pitch 0.5 mm (both side of board), 1 mm. Wire type 11

  12. AD scanner - 96 channel integrator (Al Franck) Integration time from 5 msec - 6.5 sec Dynamic range:  E10 up 16 bit ADC Noise  0.2% of full scale Calibration feature Scanner II - Z-80 based processor. Has video output.Will require software work to interface to computer. Electronics 12

  13. 5 Standard vacuum box > 10 bayonet style vacuum cans in beamlines Parts to build 5 wire plane assemblies for standard multiwires Modify and refurbish bayonet style vacuum cans - also most of them are class 1 Enough motor controllers to run 10 devices 2 spare scanners only - can multiwires be OR’d?
