Abstract: A streak tube 1A comprises an envelope 10 including an entrance faceplate 12; a photocathode 20 for converting light received from the entrance faceplate 12 into an electron; an anode 23 having an opening 23a for passing there through the electron emitted from the photocathode 20; deflecting electrodes 24 for controlling a deflection of the electron having passed through the opening 23a of the anode; and a fluorescent screen 25 for detecting a streak image due to the electron having the deflection controlled by the deflecting electrodes 24. The photocathode 20 is configured so as to be kept from directly facing the anode 23 on an axis of an electric field formed between the entrance faceplate 12 and the anode 23 or on a tube axis passing the center of the opening 23a in the anode 23 within the envelope 10. Thus, the streak tube capable of suppressing influences of noise signals on signals corresponding to incident light can be realized.

Abstract: A lamp (50) has a lamp envelope (10) having a body (12) with a bottom (14) having a lead-in accepting channel (18); a seat (22) formed with the bottom (14) adjacent one of the lead-in accepting channels; a light source capsule (51) having two electrical lead-ins (52, 54) extending therefrom and through the lead-in accepting channel (18; and an electrical contact (24) having a first depending leg (26), an intermediate transverse portion (28) including a seat engager (30) adapted to cooperate with the seat (22), and a projecting leg (32) extending away from the intermediate transverse portion (28) and along a side (34) of the bottom (16), the first depending leg (26) being in mechanical and electrical contact with one of the lead-ins (54).
