Target Hall Layout Outline

Chris Densham

(Brian Smith)


Constraints

Constraints

  • Two Main Beam Lines 10 metres apart

  • Positron Source Beam lines

    • Target AMD Pre-Acceleration system A

    • Positron CAPture system A

    • Target AMD Pre-Acceleration System B

    • Positron Pre-Accelerator

      Positron Beam Lines 2.5 Metres apart


Initial basis for remote handling

Initial Basis for Remote Handling

  • Water cooled Ti alloy target wheel assumed

  • Target changeover in hours - (short target lifetime) which indicates:

    • 2 parallel target stations and 2 hot cells

    • Modular approach - simple

    • Horizontal installation system considered (based on ISIS)


Target wheel and solenoid s

Target Wheel and Solenoid(s)


Target module outline target wheel solenoid s vacuum vessel

Target module outlineTarget wheel + solenoid(s) + vacuum vessel

Size of System

Target wheel

1 m radius – may need to increase

1 or 2 Capture Solenoids

(0.54 m Radius)

Vacuum Tank

Width 2.7 metre

Height 2.2 metre

Depth 1.0 metre

All dimensions approximate…..

2.7 m

1 m

Quick-connects to beam pipe


Baseline target module concept

Baseline target module concept

Target module vacuum vessel contains:

1 m Radius Target Wheel (reduced, if possible, from original 2m)

One (Two) Superconducting Solenoids

Vacuum vessel sealed to beam pipe, e.g. using inflatable pillow seals

Replacement of target and/or solenoids carried out in hot cell


Installation system

Installation System

  • The ISIS Horizontal type layout has been used as the starting point

  • Baseline concept is for the complete target and services system to be on rails and moved in and out of the beam

  • Vertical installation may have some advantages (space, cost) but likely to be slower to change targets


Horizontal installation layout

Horizontal Installation & Layout

  • Two target stations on the same side of the beam

  • One target system in the beam

  • Other target system retracted to the maintenance position

    • NB gap in beam pipe needs to be plugged

Issues to consider

Issues to consider

  • Large size of target hall: high cost

  • Intersecting tunnels or open plan?

  • Location of cranes?

  • Access shaft

  • Storage area

  • Disposal of failed targets

  • Separate target and solenoid support and installation?


If target lifetime is many months or years

If target lifetime is many months or years…

Target station design philosophy may change:

  • Target changeover in days or weeks

    • single target station and single hot cell may become possible

  • Modular approach still favoured

  • Vertical installation system may be possible

    • Less space required? – cheaper?


Future positron target work

Future positron target work

  • Baseline positron target design needs eddy current analysis and lots more

  • UK hasn’t done any yet

  • But we have the tools to do this sort of thing…
