This application performs some calculations related to Light Source Storage Rings. 1. It does scaling of emittance and other properties with the beam energy and number of cells, for several well-known cell designs. 2. It does calculations for the Short Pulse X-ray Scheme using crab cavities. 3. It does calculations of rf bucket parameters in storage rings. 4. It computes pole-tip field and amp-turns for iron-dominated multipole magnets. 5. Tune resonance diagrams with control of which orders and normal/skew terms.
