The reflection loss when a radiation ray passes through an empty quartz cell should be calculated. Concept introduction: When a beam of radiation passes through two medias with different refractive indexes, a fraction of the beam reflected at interface. The refraction loss is expressed as follows, l r l 0 = ( n 2 − n 1 ) 2 ( n 2 + n 1 ) 2 Where, l 0 = intensity of the incident beam l r = reflected intensity n 2 , n 1 = refractive indexes of the two media

Question

In TEM, we can obtain a diffraction pattern of a thin sample through the use of objective apertures that act as a barrier for incoming electron radiation in the microscope column. Due to the small angle that the beam makes as it transmits through the crystal planes of TEM samples, the Bragg condition can be modified to: ηλ 2d0 = Determine the wavelength of electrons travelling through an objective aperture if the diffraction spot produced satisfies the Bragg condition at (1.20x10^-2) (0 in radians) for the first order (110) plane with a lattice parameter of (6.010x10^-10), and the camera length between the CCD camera and sample is {c}.

Interpretation Introduction

Interpretation:

The reflection loss when a radiation ray passes through an empty quartz cell should be calculated.

Concept introduction:

When a beam of radiation passes through two medias with different refractive indexes, a fraction of the beam reflected at interface. The refraction loss is expressed as follows,

lrl0=(n2−n1)2(n2+n1)2Where,l0=intensity of the incident beamlr=reflected intensityn2, n1=refractive indexes of the two media
