    30303. Bio EM,JP,MB:
    31  - See cells in FaDu from all days and the higher seeding densities.
    32   - Seeing a clear dose response.
    33   - Still looks like the radiation has been too high.
    34  - No cells in HeLa.
    35   - Seem to be more sensitive.
    36   - Emma mentioned that people working with them in Birmingham at the same time as phase 2 were struggling to get results with them. So could be the cell line? However, since Emma has got back she has done more work with them and they seem fine?
    37   - Possibly worth moving to a different cell line in the future?
    38  - Cells back with Mark and he will organise their delivery to Birmingham. (Most likely after Christmas)

    3939 - Results hopefully can be produced by end of Jan
    40  - Marie is keen to stay connected. She is putting together a grant about different radiation types so this work is all useful.
    41  - Emma to share the counting software she uses with Marie
    42  - Still uncertain about the uniformity.
    43   - Comet analysis should help with this
    44    - But cells were on ice for a while before being forzen so may have repaired.
    45   - Calvin to send Emma min and max dose

    47474. Beamline Diagnostic, KL, TP, CD, PH:
    48  - RCF Update
    49   - RCF not sent up yet, so will send in Jan
    50  - KL, PH on Sparse Sci-Fi [raw-attachment: Slides]
    51   - Peter has a simulation of the fibres used (50mm long fibre polysterene core and PMMA cladding as per BCF50)
    52   - If using a remote camera recieve order of 1/1000 power from scintillation as if using a nearby screen.
    53   - Key questions:
    54    1) What is the typical light produced in a sparse fibre per laser pulse
    55     - How many protons per shot pass through each fibre
    56      - 20-30 is fine but 1 or 2 is too few
    57     - Can be done in sim but requires a better understanding of the source distribution
    58    2) Dimensions of the vacuum chamber
    59   - Instead of remote could also looking at capturing the light into a larger fibre to collect more light
    60  - Phosphor screen requires face-on viewing so possibly some practical difficulties
    61   - Peter also happy to simulate this
    62  - Using the discarded beam (Photodiode).
    63   - Beam consistency shows a Pearson Correlation Coefficient of minimum 0.83.
    64   - Predicting the average pixel count inside the cell dish from the beam outside the cell dish provides a Pearson correlation coefficient of 0.991, and can predict with a 6% error.
    65   - Better analysis to be done with dose once RCF properly calibrated
    66  - Delaminated RCF
    67   - Mark Hill has some and will take it to Birmingham tomorrow.
    68   - Will need to do a calibration of this before we start a new run
    69   - Least popular option
     48- RCF Update
