High Energy Electron Radiography (HEER) is a new method suitable for High Energy Density Physics (HEDP) research that uses a high energy electron beam as a probe for time resolved imaging measurements of high energy density processes in materials[1]. A high energy electron imaging research platform based on a 100 MeV Electron Linac (e-Linac) which was designed for experimental research of HEER has been proposed by Electron Accelerator Group in IMP. This e-Linac has two injection beam lines. One is a thermionic RF gun with Alpha magnet and quadrupole magnets, and the other is a photo-cathode RF gun with emittance compensation solenoid(Fig. 1), and parameters details is shown in Table 1. The experimental terminals of this e-linac have been designed for HEER and the Thick Target X-ray imaging.

At the beginning of 2013, the Institute of Modern Physics proposed to develop electron radiography technique based on high-energy and short-pulsed electron accelerator, which is applied to high energy density state/thick target diagnostics[1]. A low energy beam transport system (LEBT) was designed to matching the transmission between the gun and the LINAC.

High energy proton beam has the long penetration length in solid matter and it could produce the radiographsand indicate the tomography and material properties inside of the specimen. Considering the expensive coststo construct a high energy proton accelerator, the other candidate of high energy electron beam becomes moreacceptable[1??3]. Due to the high spatial and temperal resolution of high energy electron beam. It is a power tool todiagnose the inner structure change during the high energy density matter production and the inertial confinementfusion process. In order to study the density resolution of the high energy electron beam radiography, a step-targetwas designed and produced. The structure and the target pictures are shown in Fig. 1 and the Si targets withdifferent slot-width were produced by using the microetch technics.

The algebraic energy method (AEM) is applied to the study of molecular dissociation energy De for 11 heteronuclear diatomic electronic states: a3∑+ state of NaK, X2∑+ state of XeBr, X2∑+ state of HgI, X1∑+ state of LiH, A3Ⅱ(1) state of IC1, X1∑+ state of CsH, A(3Ⅱ1) and B0+(3Ⅱ) states of G1F, 21Ⅱ state of KRb, X1∑+ state of CO, and c3∑+ state of NaK molecule. The results show that the values of De computed by using the AEM are satisfactorily accurate compared with experimental ones. The AEM can serve as an economic and useful tool to generate a reliable DR within an allowed experimental error for the electronic states whose molecular dissociation energies are unavailable from the existing literature.
