Developroent of scintillator strip calorimter by DPPDD

本项目的目的是开发一种新型的光子传感器DPPD，并将其集成到粒子量热仪中。DPPD是由研究人员命名的，来自Digital Pixel Photo-Diode，然而，在与Hamamatsu公司成功开发出传感器后，他们将其命名为MPPC(多像素光子计数器)。该传感器在室温下工作良好，即使与固态光子传感器配合使用，也能对其上的光子数进行计数。研制成功，公司将其作为产品推向市场。研制成功带来了这一成果。此外，我们还生产了尺寸为1.0x4.5x0.3cm3的小闪烁体条带。计量单位的量是量热计中的468。我们已经建造了这个探测器，并在DESY/汉堡研究所进行了测试。结果已经在许多地方向公众开放。

The purpose of this project is to develop new type of photon sensor named DPPD and integrate it to a particle calorimeter. The DPPD is named by the investigator, from Digital Pixel Photo-Diode, however, after successful development of the sensor withe Hamamatsu company, they named it as MPPC (Multi Pixel Photon Counter). This sensor works fine under room temperature even with solid state photon sensor, which is able to count the number photons on it The development proceeded successfully and the company open it as a product to the market The successful development brought this achievement Furthermore, we have produced small scintillator strip which size is 1.0x 4.5 x 0.3 cm3. The amount of the measurement unit is 468 in a calorimeter. We have constructed this detector and tested at DESY/ Hamburg institute. The results are already open for public at many places.
