The methodology for active testing of electronic devices under the radiations

Abstract

The meth od ol ogy, de vel oped for ac tive test ing of elec tronic de vices un der the ra di a tions, is pre sented. The test set-up in cludes a gamma-ray fa cil ity, the hard ware board/fix tures and the soft ware tools pur posely de signed and re al ized. The meth od ol ogy is so wide-rang ing to al low us the ver i fi ca tion of dif fer ent classes of elec tronic de vices, even if only ap pli ca tion ex am ples for static ran dom ac cess mem ory mod ules are re ported.Key words: test ing methodology, elec tronic de vice, to tal ion iz ing dose, sin gle event ef fect, gamma ray A.

Response of GAFChromic® HD-V2 film dosimeter in 10-300 Gy dose range for radiation testing of electronic devices

“…To get a 2 Gymin -1 dose rate, only 3 sources with lower ac tiv i ties were ex posed. In [15][16][17]34] are avail able de tailed infor ma tion, pho to graphs of the fa cil ity high light ing source lead con tainer, ex po sure de vices, ir ra di a tion area and a work ing ta ble where ex po sure of elec tronic de vices can be re al ized. The struc ture is equipped with do sim e ters, to as sure a safe func tion ing and pre cise dose mea sure ment and is able to of fer a good ver sa tility to carry out sev eral typologies of ir ra di a tion tests.…”

“…To reach a given RRL, dif fer ent test con fig u rations must be pro vided for each ap pli ca tion. Dur ing its func tion ing, a com po nent was nor mally ex posed to ra di a tion field, with a do sim e ter placed on the com ponent to eval u ate the de vice ab sorbed dose value, while power sup ply and aux il iary cir cuits were pro tected by lead shields [17].…”

“…Gafchromic HD-V2 films are in ter est ing as re liable do sim e ters for mea sure ment of ab sorbed dose in ra di a tion test ing of elec tronic de vices, one of our research ac tiv i ties aimed to study the ef fects of gamma radi a tions on elec tronic com po nents used, in par tic u lar, for space ap pli ca tions [15][16][17]. In this field, main dosim e ters used for ra di a tion test ing of elec tronic de vices are thermoluminescent do sim e ters, ion iza tion chambers, semi con duc tor do sim e ters, poly mer alanine dosim e ters, perspex do sim e ters, and radiochromic do sime ters.…”
