In the devices described are recorded tracks of particles whose mass is expressed in atomic mass units, 1/12 C = 1 Da, or fractions thereof. Proton, neutron, antiproton - the approximate weight is one Dalton, electron and positron - approximately 1/1000 Da. The particles are moving mostly in a magnetic field.
Katika vyombo vya ilivyoelezwa ni kumbukumbu nyimbo ya chembe ya molekuli ambaye ni walionyesha katika vitengo vya atomi, 1/12 C = 1 Da, au sehemu yake. Proton, nutroni, antiproton - uzito takriban ni moja Dalton, elektroni na positron - takriban 1/1000 Da. chembe ni kusonga zaidi katika uwanja magnetic.
