Alanine dosimetry ESR(EPR) equipment

ESR X10SA Version2	Alanine molecule. Amino group (NH2-) in the molecule comes off by high energy irradiation and I become radical and show a special ESR spectrum. The method of estimating the exposed dose measuring this amount of the radical is called ESR dosimeter.

Feature

• It is very compact size (28(W) x 26(D) x 35(H)cm). It is the portable ESR device, easy to use on the site.
• It has the measurement sensitivity more than standard type X band ESR system.
• The miniaturization of about 27kg in weight was achieved by the adoption such as rare permanent magnets.
• That is, for process monitoring, desktop PC by ESR handheld sensor, remote measurement, and utility applications.
• Single target specification: We design the magnetic field, the frequency, and the output, etc. according to your requirement.

Measurement by PC

If You connect a PC on hand and turn on a power supply, Resonator Adjusting Window appears automatically, and measurement operation is started.

		Mesurement window

• The resonance characteristic is adjusted with Resonator Adjust Window, the measurement condition is controlled with Condition Setting Window, and after the setting, everything is controlled with Measurement Window.
• It multiplies according to the purpose, and the blank data and the correction, etc. are set.
• The moving average can be selected.
• Data processing (height h of the peak and one time & integration etc. twice) can be specified.
• A target point is read in the cursor line. (Refer to the chart. )
• The automatic compensation of magnetic field strength can be done at the signal position of Mn2 +.
