MINERnA Prototype Studies

MINERnA Prototype Studies

• Robert Bradford
• Jupiter/MINERnA Group Meeting
• November 16, 2005

2
Overview

• Introduce Dan Ruggiero
• Reminder about the prototypes
• Goals for the next 8 weeks
• Calendar
• Comments/feedback...

3
Dan Ruggiero

• Grew up near Albany, NY
• Went to Albany State in Materials Science before
  grad school at UofR.
• Been an HEP technician for 15 years worked on
  CMS for last 9 years.

4
A little more...

• Hes a swimmer.
• Naval reserves for 4 years assigned to mine
  sweeper. Has already removed mines from 15X.
• Likes Thai food and most things spicy.
• Helped with the CMS garden at FNAL, producing a
  bumper crop of rutabagas.

5
Whats he doing in Rochester?

• Enjoying last bits of fall in the Northeast.
• Hiding from the rutabagas.
• Dan will be at UofR for the next 2 months to help
  plan the MINERnA assembly process.
• Well use wooden prototypes to mock up module
  assembly

6
A Basic Module
Steel Frame
Mounting ears
Lead Collar
Fiber connectors and mounting hardware
Scintillator planes or calorimeter targets
Load-bearing spacer
Scintillator for calorimeters
WLS fibers
7
Fleshing out assembly...

• Will mock up module assembly with wooden
  prototypes.
• We need to decide
• Exact order of steps
• Hardware stock and specialty
• Tooling
• Handling issues
• Risk for technicians and detector components

8
Basic module assembly

• Receive frame from WBS8 on strongback
• Inspect frame before scintillator installation
• Install mounts for clear fiber connectors
• Install OD scintillators
• .....

• We still have to decide
• Is the obvious procedure going to work?
• What ordering makes most efficient use of
  labor?
• What are the detailed steps required along the
  way?
• Is the layout of assembly space properly
  optimized?

9
Nuts and bolts

• Basic design work is not detailed at the
  nut-and-bolt level yet.
• We need to
• Decide what hardware/connectors we will use the
  hold the parts together.
• Identify what pieces need to be specially
  designed and fabricated.
• Step through the assembly procedure with mocks of
  all hardware (including specialty pieces) 2-3
  times to evaluate their performance.
• By January, provide conceptual design of pieces
  to Bob Flight.

10
Tooling

• Need to idenfity
• What tools well need
• What tools does UofR already own and what will
  need to be purchased
• Do we need to design any custom jigs?
• What safety training will be required
• FNAL guidelines/classes
• What specific training will we need to provide
  techs

11
Handling/Risk

• We will evaluate
• What safety gear is needed?
• How safe is the procedure?
• How can we minimize risk to techs and components?
• What are QA strategies for finished modules?

12
Other points

• Will be basis of our preparations for next
  summers full module construction at FNAL
• Well provide feedback to other task groups based
  on our experience.
• Will start to plan module mapper
• Will report to collaboration in January.
• PMTs
• will remodel PMT rack based on new frame
  dimensions
• finalize maintenance/handling procedures for
  PMTs
• provide updated clear cable lengths

Summary/Conclusions

• Dans very experienced and will be very useful
  over the course of the next 2 months
• Assembly should be well thought out and practiced
  by the end of the studies
• Ill write an engineering document after its all
  over.....
