1. G.Barber: Mice-International Meeting 2-7-20031 Plans for Sci-Fi Prototyping. Contents:- Mechanical Layout of Sci-Fi Design of the Fibre Optic Connectors Design Issues Still to be Addressed Future Plans This work is being undertaken by Imperial College and Liverpool University physics Department (Peter Cooke), Fermilab (Alan Bross), KEK (Koji Yoshimura), Osaka (Yoshi Kuno, Akira Sato) And others too numerous to mention here but you know who you are -thank you

2. G.Barber: Mice-International Meeting 2-7-20032 Mechanical Layout of Sci-Fi A Reminder of the Layout of the 5 Stages ?

3. G.Barber: Mice-International Meeting 2-7-20033 Reasons to build the Sci-Fi Prototype The aims of the Single stage prototype will be to:- Prove the feasibility of the design Solve any production problems Try to develop more efficient (and cheaper if possible) construction techniques Ensure that all stages can be made exactly the same Test the efficiency of the light guide connectors To create a working detector to allow full system functionality to be developed

9. G.Barber: Mice-International Meeting 2-7-20039 Design of the Fibre Optic Connectors The fibre optic connector design is governed by the following factors :- Multiplexing Layout of Sci-Fi ‘Stringing’ feasibility of the Connectors Cost, ease of manufacture and delivery Available space

10. G.Barber: Mice-International Meeting 2-7-200310 Design of the Fibre Optic Connectors The 1 st Iteration… This had 126 - 380  holes which where so close that it is impossible to mould not to mention that they would need to have the fibres threaded in the correct order.

11. G.Barber: Mice-International Meeting 2-7-200311 Design of the Fibre Optic Connectors The 2nd Iteration… This has a diagonal stagger to maximise the distance between the holes (it was still not enough) AND STILL 126 separate 350  fibres Need to be threaded per connector!!!

12. G.Barber: Mice-International Meeting 2-7-200312 Design of the Fibre Optic Connectors The 3rd Iteration… This has a diagonal stagger to maximise the distance between the holes but more important is that it multiplexes at the stage. This means that the fibres will be threaded in bundles of 7 from the Fibre plane and all subsequent units will have 18 1mmØ fibres.

15. G.Barber: Mice-International Meeting 2-7-200315 Design of the Single Stage The aim, as already stated, is to have all the stages the same. This means that there is only one development programme. Further advantages are:- that the amount of spares can be minimum All stages are interchangeable should it be necessary to fit a less efficient stage in a less critical position Production will be easier

16. G.Barber: Mice-International Meeting 2-7-200316 Work in Progress We have now put a line under the construction of the model and will concentrate on the Prototype detector. To this end trials are taking place to lay-up the fibres in the required format and we will be visiting Alan Bross with a view to speaking with the experts who have developed the techniques and adapting them for 350  fibre.

17. G.Barber: Mice-International Meeting 2-7-200317 The Laying Down of Fibres This is our 1 st attempt to lay the fibres parallel using a PTFE grooved plate. PTFE Bonded to an Aluminium Block 200  Grooves under a Microscope A Small Array of Fibres Laid Out and Bonded

18. G.Barber: Mice-International Meeting 2-7-200318 Issues Needing to be Addressed Detailed design of tooling for the manufacture and assembly of the stages How to lay down the fibres to a known accuracy (this is being addressed) Light transmission of the connectors Multiplexing (is this the correct approach) Fixing and sealing into position

19. G.Barber: Mice-International Meeting 2-7-200319 Future (short term) Plans To define and build the prototype stage whilst addressing the manufacturing problems To design and develop the tooling for the carbon-fibre structures To further develop the fibre-optic connector To develop assembly and installation procedures ???

20. G.Barber: Mice-International Meeting 2-7-200320 Schedule This is still our schedule and it is still very tight. The good thing is that everybody is pulling together and we have received offers for machine shop effort which we hope to pursue. A big thank you also to all for advice freely given
