Chiba was responsible for the PMT and EHE simulation programs and many of our service tasks are related to these business. The detector simulation project, Romeo, which is also responsible for the DOM’s acceptance calculation to be implemented in the Photonics, is maintained by our group (S. Yoshida, K. Mase) who includes one of the original authors of Romeo (S. Yoshida).
The detector calibration using the standard candle has also been on our priority to provide the collaboration with some key knowledge of our detector response. K.Mase, S.Yoshida, M.Relich, maintain this activity to have better understanding of the DOM response and the ice propaties. M.Relich works on the flasher and SC data for improving the IceCube's handling of saturated waveform signals. A.Ishihara maintains responsible for the SC data filtering to remove chance-coincident muon events for calibration analyses use.
Our other service activities include co-chair of diffuse-atmos WG, charge timing extractor module, Portia, (A. Ishihara), which is alternative to WaveReform for processing large pulses in DOM. This module has been frequently used in EHE and monopole analysis that must handle extremely luminous events. The EHE simulation framework/meta-project is maintained by K. Mase and S. Yoshida.
Chiba also works on EHE filters that contain most energetic population of IceCube events. The filtered data are compared with simulation (A. Ishihara/S,Yoshida) for confirming our detector response and its stability to high energy data.
Because the present EHE signal search procedures are not CPU-intensive, R.Gaior is working on implementing the quasi-online signal selection pipeline for sending alerts to other astronomical instruments. The online search for extremely-high energy neutrinos allows IceCube to trigger follow-up observation by optical/gamma-ray telescopes. A,Ishihara is now developing the suitable algorism and estimating the resultant sensitivity.
T. Kuwabara participates the effort to measure atmospheric neutrino fluxes. He also provides an interface to the SuperK collaboraion for unified analyses with their data.
Our analysis efforts are mainly focused in search for extremely-high energy neutrinos. K.Mase and the graduate student (K.Owaku) are interested in improving the detection efficiency by making appropriate corrections for PMT saturation.
Chiba’s capability for MC data production has been improved. We work on ultra-high energy Corsika simulation and Juliet signal simulation. As network bandwidth from Japan to US is limited, we transfer data to Madison by shipping USB disks. K. Mase maintain this service activity.
