Answer #1

Mostly for this type of object of very high temperature only thermocouples are used as sensor to measure such high temperature among a cold an hot juction on the body surface.Nickel-chromium or Nickel-Alumel is mostly used as the material for sensing elements as it can withstand high temperature without getting melted and getting oxidized with the elements like water and oxygen of the environment and can be used across various range of temperature also called as type K sensors.

The wavelength of peak emission from any star is related to the temperature of its photosphere (i.e., the emitting surface) by Wien’s Law, given by λ = 2,900/T, where λ is the wavelength in micrometers (1 µm = 10-6 m), and T is the temperature of the star in Kelvin (see textbook’s figure 3.27 for help). Answer the following questions using the above equation. 2.1. The most massive star ever observed is a Wolf-Rayet type-star, named R136a1. It is so...

The emission wavelength of such a scintillator lies between 275 nm and 450 nm and the light yield per neutron is reported to be 20000 photons/MeV neutron energy. Now, you are asked to help design a new photodetector, which receives the light emitted from that scintillator. What largest work function of a material used for a photo cathode would be acceptable that still allows detection of an emission originating from the scintillator?
