Izinsiza kusebenza ze-LEEM-3 Electrostatic Field Mapping
Kubuchwepheshe bobunjiniyela, kuyadingeka kaningi ukwazi ukusatshalaliswa kwensimu kagesi kohlelo lwe-electrode ukuze kufundwe umthetho wokunyakaza wama-electron noma izinhlayiya ezikhokhisiwe emkhakheni kagesi. Isibonelo, ukuze ufunde ukutadisha nokugxeka ugongolo lwe-elektroni kushubhu ye-oscilloscope, kubalulekile ukwazi ukwabiwa kwensimu kagesi ye-electrode kushubhu ye-oscilloscope. Emhubheni we-electron, kudingeka sifunde umthelela wokwethulwa kwama-electrode amasha ekuhambeni kwama-elektroni, futhi sidinga nokwazi ukusatshalaliswa kwensimu kagesi. Ngokuvamile, ukuze kutholakale ukwabiwa kwensimu kagesi, indlela yokuhlaziya kanye nendlela yokulingisa yokulingisa ingasetshenziswa. Kepha ezimweni ezimbalwa ezilula kuphela lapho ukusatshalaliswa kwensimu kagesi kungatholakala ngendlela yokuhlaziya. Ohlelweni olujwayelekile noma oluyinkimbinkimbi lwe-electrode, imvamisa kunqunywa ukulingiswa kokulingisa. Ububi bendlela yokulinga yokulingisa ukuthi ukunemba akuphezulu, kepha ekwakhiweni kobunjiniyela okujwayelekile, kungahlangabezana nezidingo.
Imisebenzi
1. Funda ukutadisha izinkambu ze-electrostatic usebenzisa indlela yokulingisa.
2.Julisa ukuqonda kwemiqondo yamandla namandla wezindawo zikagesi.
3. Imephu yemigqa ye-equipotential kanye nemigqa yensimu kagesi yalokhu okubili amaphethini we-electrode we ikhebula le-coaxial kanye nezintambo ezimbili ezihambisanayo.
