SPECIFICATION
| Should be suitable to find the charge-to-mass ratio of electrons and to reproduce J.J. Thomson's experiment. |
| (1)Should have 90 degrees rotatable tube with an electron gun |
| (2)Should have a 15-17 cm radius Helmholtz coil to produce a magnetic field. The coil number of turns should be 120-140 turns. |
| (3)Maximum current should be 3 - 4 Amp. and filament voltage should be between 6 - 7 VAC |
| (4)Acceleration voltage between 0 - 200 V and tube diameter between 15-16 cm |
| (5) The electron beam should be sharp and visible |
| (6)Should have a fluorescent/illuminated scale behind the beam to read electron beam diameter and to reduce parallax errors. |
| (7)Should have a rotatable tube for the study of electrons in a magnetic field. |
| (8)Should have two Helmholtz coils, a helium-filled electron tube |
| (9)Should have deflection plates to study the effect of an electric field on moving electrons |
| (10)Should have tunable DC constant current power supply |
| (11)Should have tunable DC constant voltage power supply |
| (12)Include two digital multimeters and required patch cords. |
| (13)Coils and rotatable tubes should be mounted on a base |
| (14)Should provide manufacturer catalogue with the offer |
