HKS and HES (HKS-HES) Wiki

This is the Wiki for Jefferson Lab experiments E01-011 and E05-115. Eventually, it should contain detailed descriptions of all hardware and software components.

All information relevant for shift crews should be contained or linked to from the page Shift Crew Information.

Collaboration

HKS-HES web page is opened at http://lambda.phys.tohoku.ac.jp/~hes. It is opened for public and this Wiki is for JLab user only. The web page information is still just copy of HKS page now, but we will update.

Accelerator & Engineering

This section of the HKS-HES Wiki contains an overview of the scope of work being performed by Accelerator and Engineering staff in support of the experiment. The section is divided into system-specific sub-sections.

High resolution Kaon Spectrometer (HKS)

This section contains information about magnets and detectors of the kaon spectrometer.

Fission Experiment

This is the experiment (E02-017) which will measure the lifetime of heavy Lambda-hypernuclei that are produced via photo-production using the real photons generated from the HKS target. The experiment will run parasitically with the HKS experiment and the Fission Fragment Detector (FFD) is located just in front of the photon dump for HKS. The FFD contains its own target foil with multiple thin materials, Fe, Cu, Ag, Au, Bi, and U, on a common backing foil (2 microns thick) aluminum-Mylar. In the common chamber, the FFD has two independent pairs of MWPCs to measure the TOFs as well as the trajectories of the fission fragments. The system operates under low pressure (~3 Torrs) with heptane gas.

Technical information associated with the experiment are provided here.

F1 TDCs

Hardware

The F1 TDCs are installed in the electronics room of the counting house. One crate operates in high resolution mode, using only 1/2 of the inputs, and the other one in low resolution mode. The F1s are unusual TDCs and have a number of peculiarities that need to be accounted for.

For an overview and all the detail you might want, take a look at this Wiki page from the GEp-III experiment: F1 TDC Details
All the special consideration for that experiment also apply to HKS.

Controls

CAEN High Voltage System

We use the CAEN HV crates in the G0 cage on the 2nd floor of the counting house.

Analysis

Raw data files are analyzed with the HKS/HES Analysis ENGINE, a modified version of the Hall C Analysis ENGINE.

A list of runs can be found in the E05-115 Run List
