First outline from Dr. Horn, on 07/07/2013.
In green are comments from Marco, on 07/08/2013.
Paper Outline: KAON AEROGEL CERENKOV DETECTOR
INTRODUCTION
- Introduction to physics and infrastructure, i.e., spectrometers in Hall C
- Cite other experiments (approved) that also require the detector?
DESIGN CONSIDERATIONS
- Experiment requirements and motivation for aerogel detector
- Design choices
- threshold vs. RICH
- box dimensions and PMT placement etc.
- choice of aerogel radiators
- impact on other detectors, e.g., delta electrons
- impact on other detectors: multiple scattering calculation
CONSTRUCTION AND COUNTER LAYOUT
- Details of the detector box and tray construction
- Motivation and explanation of materials used in the construction, i.e., aluminum, honeycomb, etc.
- Details on the fabrication and construction
- Construction of a frame to hold aerogel in center of box for cases where box not entirely filled
- Short description of detector components
- Choice of reflective materials, wires to hold aerogel, etc.
- Aerogel used, i.e., manufacturer
- PMTs (geometry, properties, details on their installation in detector, i.e., magnetic shielding, aluminum cylinders etc.)
- Construction of a single counter (Prototype) and tests performed with it
- photoelectron yield for different refractive indexes
- photoelectron yield for different thickness (number of tiles) of aerogel
AEROGEL STUDIES
- Characterization of aerogel tiles
- Variation of dimensions and refractive index tile-to-tile and batch-to-batch
- Optical measurements (transmittance etc.)
- Photon Yield
- Humidity effects on aerogel (if available on time)
PHOTOMULTIPLIER TUBES STUDIES
- Measurements of quantum efficiency and photocathode uniformity
-> Do we have Q.E. measurements? Was HMS PMT measured for Q.E.?
MC SIMULATIONS
- Description of the simulation(s) performed, e.g.,
- predictions of photoelectron signal
- uniformity of signal
- average number of PMTs that trigger per event
- timing resolution of detector
- Light collection efficiency
PERFORMANCE
- Results from cosmic measurements
- signal from 1.030 and 1.015 aerogel, single column(?)
- 1.030 to 1.015 signal ratio, for single column of aerogel (can add calculation, prototype and MC ratios for comparison?)
SUMMARY AND OUTLOOK
- Possibility of improvements:
- additional tray with even lower refractive index (when material becomes available)
- Installation and tests with beam to come
