DENKA M3 LaB6 CATHODE HITACHI
Standard (Round) Tips
Provided with a 90° cone and 15µ radius round tip.
Flat (Truncated) Tips
Flat tips are recommended for applications where stability and long lifetime are the prime considerations, and where some degree of brightness can be sacrificed. Flat tips are available in eight configurations:
90° Cone Angle | 60° Cone Angle |
20µ radius | 20µ radius |
40µ radius | 40µ radius |
60µ radius | 60µ radius |
100µ radius | 100µ radius |
Sharp Tips
Sharp tips are recommended for applications where initial brightness is the foremost consideration and where shorter lifetime can be accepted. Sharp tips are available in two configurations.
- 60° Cone Angle
5µ radius
10µ radius
Flat Tip | Standard (round) Tip | Sharp Tip | |
Brightness | About 5 times that of tungsten, 2-5x105 A/cm2· Str |
About 10 times that of tungsten, 1x106 A/cm2· Str |
Twice as bright as standard tips 2x106 A/cm2· Str |
Saturation | Mono spot at about 1,400°C | Mono spot at about 1,500°C. | Almost the same as standard tips |
Crossover | Large (11-13µ) | Small (7-10µ) | Small (7-10µ) |
Angular distribution | Broad, 3.3-4.2x10-2 rad | Sharp1.6 x10-2 rad | Sharp1.6 x10-2 rad |
Used Temperature | Low temperature | Low temperature | High temperature. |
Lifetime | Long life; usable at low temperatures and crystallized end changes slowly. | Long life but shorter than flat tips. | Short |
Operation | Easy; thanks to its large spot size and broad adjusting range. | Not so difficult. | Difficult; Point adjustment needed! |
Stability | High; vulnerable to thermal expansion or vibration. | High | Middle;. Vulnerable to the thermal expansion or vibration. Adjustment is sometimes necessary. |
Technology Needed | Ordinary | High | Very high |
Provided with a 90° cone angle and a 15µm radius round tip. These are just the standard Denka LaB6 Cathodes that are in stock.
