摘要： A high-energy ray detector includes a detection unit in a vacuum container. The detection unit includes a first electron multiplier, a second electron multiplier, and an electron collector. Each of the first electron multiplier and the second electron multiplier has one or more MCPs each configured to emit electrons by interaction with an incident high-energy ray (γ-ray, X-ray (in particular hard X-ray), or neutron ray), and multiply and output the electrons. The electron collector is transmissive for the high-energy ray. The electron collector is configured to collect the electrons multiplied and output from each of the first electron multiplier and the second electron multiplier, and output an electric pulse signal.

摘要： The present invention relates to a photomultiplier having a structure for making it possible to easily realize high detection accuracy and fine processing, and a method of manufacturing the same. The photomultiplier comprises an enclosure having an inside kept in a vacuum state, whereas a photocathode emitting electrons in response to incident light, an electron multiplier section multiplying in a cascading manner the electron emitted from the photocathode, and an anode for taking out a secondary electron generated in the electron multiplier section are arranged in the enclosure. A part of the enclosure is constructed by a glass substrate having a flat part, whereas each of the electron multiplier section and anode is two-dimensionally arranged on the flat part in the glass substrate.

摘要： A silicon substrate 12 has a main face in a (100) plane, whereby a fracture 17 generated from a molten processed region 13 acting as a start point extends in a cleavage direction of the silicon substrate 12 (a direction orthogonal to the main face of the silicon substrate 12). Here, a rear face 1b of an object to be processed 1A and a front face 10a of an object to be processed for separation 10A are bonded to each other by anode bonding, whereby the fracture 17 reaches a front face 1a of the object 1A continuously without substantially changing its direction. When generating a stress in the object for separation 10A, the fracture 17 has reached a rear face 10b of the object for separation 10A and thus easily extends toward the object 1A.

摘要： A gamma ray detector is a detector detecting gamma rays and includes a photomultiplier tube having an entrance window and a photoelectric surface. The entrance window is a Cherenkov radiator. The photoelectric surface is formed on a vacuum side of the entrance window via an intermediate layer. The thickness of the intermediate layer is equal to or less than the wavelength of Cherenkov light emitted by an interaction of the gamma rays with the entrance window.

摘要： An electron tube includes a housing having an internal space airtightly sealed, and an electrode configured to generation or detection of energy by electron emission in the internal space. The housing has a main body part made of an insulating material and formed with a recess constituting the internal space, and a lid part fixed to the main body part so as to close an opening of the recess. The recess expands toward the opening side. The main body part is fixed with a penetrating member that is electrically connected to the electrode and passes through the main body part. The penetrating member has an internal space projecting part that projects from a bottom surface of the recess into the internal space.

摘要： A laser processing apparatus 1 is an apparatus for forming a modified region R in an object to be processed S by irradiating the object S with laser light L. The laser processing apparatus 1 comprises a laser light source 2 that emits the laser light L, a mount table 8 that supports the object S, and an optical system 11 that converges a ring part surrounding a center part including an optical axis of the laser light L in the laser light L emitted from the laser light source 2 at a predetermined part of the object S supported by the mount table 8. The optical system 11 adjusts a form of at least one of inner and outer edges of the ring part of the laser light L according to a position of the predetermined part in the object S.
