## Description

```text
JUMP ITERATE unittest

The instrument uses JUMP ITERATE to let each particle make n='jumps' returns
to the monitor. The particles have unit weight and hence the intensity scales
with the simulated statistics. (Use input parameter Ncount for setting the stats).
```

## Input parameters

Parameters in **boldface** are required; the others are optional.

| Name | Unit | Description | Default |
|------|------|-------------|---------|
| Ncount | 1 | Specify statistics | 1000 |
| jumps | 1 | Number of jumps | 10 |
