radiation, by way of them through the first

element.

The quality of the radiation absorber used by a metal plate, crimped to the base 1 1 of the core plate, is a constructive base of the entire device.

Actuator 12, for example, is kinematically connected to one of the rods; upward platforms, for example, using 1) 1 and 13.

The axes of the rotation axis of the pads 6 and 7 are labeled O respectively. and O. The axis of one of the pads 7 is mechanically connected with the sensor of the angular position of the plane, for example, with the angle-code sensor 14.

Regulated attenuator, working with radiation P1, I have 1 1, it has an arbitrary polarization (figure 2,;, contains the first attenuator 13 and the second attenuator 16, s. P; hl1cie respectively reflecting element 1,2,4, 5 and 17 - 2 {. Reflecting on the ground} yy of the first attenuator of the iojiox (eiu-i on the rotations of the 6x7 pads) 7. From 1 a l: l a; -P1e elements of the second weaker 16 are located on the rotating heads for 5 – ax 21 22. The axes of the enemy vrap1u1vdhs Sh1O1tsadkad first weakener 150 and O are mutually perpendicular to the axis (), About the enemy (the rotary pad 21,22 second weakens ate 16. Kinematic the communication of the rotating pads of the first 15 and the BTojioro 6 attenuators is carried out through gear} ps1 13, found the first drive shaft 12, the kinematic link between the bristles 9 and the first table 7 nepTioi o attenuator 15, and the gear 23 table 21 of the second weaker 16.

A kine; 1 tic connection of rotating sites (adok 21 and 22; at the second attenuator 16 is carried out as in the variant described for the first attenuator 13 with the help of uniform gears 23, - 24J mechanically connected with platforms 21 and 22, respectively.) 1p meeting the conditions of simultaneous change of the angle of rotation of the branches; the ayushch1kh elements 1,2 the gear ratio of the gears 8 and 9, 9 and 23 and 2 is chosen equal to 1: 1. The absorbers of radiation 10 and 23 are installed between the reflecting elements 1 and 2, and also 17 and 18 in the cross section of the radiation beam passed through the element 1 and 17, respectively.

The faces of elements 1 and 4, and 5, 17 and 19, and also 18 and 20, which are facing each other, are mutually parallel. The angular position of the rotating pads of the attenuator is determined by the sensor 14 of the type angle - the code whose axis is connected to the rotary platform 7 of the attenuator. Structurally, the rotation units of the rotation of the platforms 6, 7, 21, 22, drive 1l, the angle-position sensor 1 of the fastener-i on the base of the attenuator 11.

The device works as follows.

The beam 3 of the blasted radiation, having a power P (Fig. 1), falls on the first reflecting face 1 of the element 1 at an angle qj, the magnitude of which is determined by the angular position of the beam 6 relative to the direction of the beam propagating radiation 3. 15. The angle of the angle f varies nyTeNt supplying the control pressure to the prgod 12, lipaiueFuie

The pinion 13, Zak1) blind on the PePlu drive, results in equal rotation of the plates 6 and 7 of the attenuator equal in magnitude and opposite in sign, accompanied by a change in the angle within, for example, 10 - 80.

Since the sprinter is 1 1 with the faces of elements 1 and 2 oriented between themselves at an angle equal to twice the fp angle of the beam of the beam on the reflect 11 c-n1 element 1, and the surfaces of elements 1 and 4, as well as elements 5 and 2 are parallel, the angle Tade1P1 of the beam weakened by the power on Kaxfu-ni from elements 4.5 and 2 is also affected in any positiv of drive 12.

Due to the fact that the prior art attenuator works on the reflected beams are also eliminated in comparison with the rtpo type of negative phenomena, they influence the accuracy of the setting of the seam of the attenuation coefficient, as distortions of the spatial structure of the radiation beam caused by rerouting 1 ;: In a separate layer (ah, norjioi tennH and scattering of radiation in the material of ttlastin, and the attenuator spectral range increases.
