| Line 3 was replaced by lines 3-7 |
| - !Results: |
| + The switch heater output is specified 0-100 mA at 100 Ohm, which gives |
| + a maximum heater power of 1 W. The MA09 switch heater resistivity is |
| + 205 Ohm. As the current source has a limited voltage (17 V), the full current |
| + over the heater is no longer 100 mA, but only 83 mA. However, this gives an |
| + increased maximum power of 1.41 W. |
| Line 5 was replaced by line 9 |
| - * Without lamda stage (coil at 4.2 K), a heater power of 0.81 W (13 V, 63 mA) |
| + * Without lambda stage (coil at 4.2 K), a heater power of 0.81 W (13 V x 63 mA) |
| Line 7 was replaced by line 11 |
| - * With lamda stage (coil at 2.3 K), a heater power of 1.06 W (14.7 V, 72 mA) |
| + * With lambda stage (coil at 2.3 K), a heater power of 1.06 W (14.7 V x 72 mA) |
| Removed line 9 |
| - * The maximum switch heater power (205 Ohm switch heater) is 1.41 W (17 V x 83 mA). |
