Introduction

Takumu Iwanaka is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of charged particle detection and radiation measurement. With a total of 2 patents, Iwanaka's work is recognized for its innovative approach to enhancing detection technologies.

Latest Patents

Iwanaka's latest patents include a charged particle detector and a radiation detector. These devices are designed to obtain observation images with correct contrast without saturation, even when the number of signal electrons incident on the detector increases due to a higher primary electron beam current. The charged particle detector features a scintillator that detects signal electrons emitted when a specimen is irradiated with primary electrons, converting these electrons into light. Additionally, a light detector is employed to detect the emitted light, with a light guide positioned between the scintillator and the light detector. Notably, the area of the light detection surface is larger than that of the signal electron detection surface.

The second patent focuses on a device for detecting charged particles or radiation. This detection device is equipped with a scintillator that converts the detection target into light, a light detector for capturing the emitted light, and a light guide situated between the scintillator and the light detector. A blocking part is also included to obstruct a portion of the detection target incident on the scintillator or the light emitted from it.
