Abstract: HA.00016 : Automatic control of microscope for double hypernuclei detection in nuclear emulsion sheet*
(Advanced Science Research Center, JAEA)
Double hypernuclei (S=-2 nuclei) are important object to study the system with strangeness -2. We use nuclear emulsion sheet to detect them. The emulsion sheet is able to record the formation and the decay of S=-2 nuclei. When we take image data via microscope, the data becomes as much as 10 terabytes with 1 emulsion sheet.
In the past experiments as KEK-PS E373, we succeeded to found the interaction energy between lambdas on a 6He_LL for the first time in the world. However, it took several years for the search of S=-2 nuclei, because human have to watch the microscope image in Personal Computer.
On J-PARC E07 at J-PARC, it was designed to obtain ten times more S=-2 nuclei than those of previous experiments within 2 years. Furthermore, we aim at 100 times statistics of the previous experiment with "overall scanning method"(VP), which will be applied for the whole area of the emulsion sheet by image taking with high speed microscope and image processing to find typical topology of S=-2 nuclei.
The scanning system of the VP and some results will be introduced in detail.
