The gamma ray source was put on the NaI surfaces so that peaks could clealy appear where we expected.</p> <p>We fitted them with gaussian and exponential, and integrate the peaks to calculate yields. The results were pretty good. </p> <p>However, at the test experiment last year, some NaI gains gradually shifted lower and peaks moved left during the beam time. So we need to let threshold level of CFD down NaI2 and NaI3 and NaI5, or change the fast amp gain and use downscaler, otherwise the part of peaks may go down below the threshold.</p> <p>Probably NaI works have almost finished before setting up geometry I hope.</p></td> </tr> </tbody> </table> </p><p> </p>
