What is the working principle of tungsten alloy multi-leaf collimator? Let's begin with some pieces of information of multi-leaf collimator. Tungsten alloy multi-leaf collimator, which was developed to replace the traditional lead blocks, are used on linear accelerators to provide conformal shaping of radiotherapy treatment beams. And specifically, conformal radiotherapy and intensity modulated radiation therapy can be delivered using multi-leaf collimators. The multi-leaf collimator has movable tungsten alloy leaves to block some fraction of the radiation beam. Typically, multi-leaf collimators have 52-160 tungsten alloy leaves, arranged in pairs. So, what is the working principle of tungsten alloy multi-leaf collimator?

Tungsten alloy shaped charge liner is one of the key parts of the high explosive anti-tank warhead, whose performance will directly affect the quality of the jet. Tungsten alloy shaped charge liner has the advantages of high melting point, high density, high sound velocity, good ductility, and high jet velocity. Wherein, high density and good ductility ensure that the jet can be fully stretched without breaking before erosion. And high jet velocity can reduce the effectiveness of the reaction armor. However, such a shaped charge liner also has the disadvantages of lower total jet length and sensitivity to radial disturbances.

Tungsten alloy multileaf collimator firstly used tungsten alloy leaves to shape structures in 1965 and has improved rapidly to modern day operation in radiotherapy. Tungsten alloy multileaf collimators are now widely used and have become an integral part of any radiotherapy department as they have strong shielding performance against rays while ensuring high accuracy. A pair of tungsten alloy leaves can form a rectangular irradiation field, and multiple pairs of tungsten alloy leaves can be combined to form an irradiation field of any shape.

Tungsten alloy is the most proper material for core material of armor piercing shell. Why tungsten alloy has a wide application as the core material in armor-piercing projectile? Tungsten alloy has high strength and good toughness, and is easy to be processed into cores with large length and slenderness ratio to achieve a large penetration depth and high penetration efficiency. Also, it has good terminal ballistic power and acceptable cost.
