The beam in Indus-2 SRS is ramped from injection energy to an energy of 2.5 GeV. The overall ramping process is implemented in multi-layer & distributed control system of Indus-2. Increasing the beam energy requires ramping of magnetic fields of total 117 magnet power supplies and 6 RF cavities synchronously. This process involves ramp profile data generation for each power supply based on user defined profile breakpoints and then synchronously setting these profiles as per user defined clock rate.

Deviation, if any, occurring during the ramping process, could be the potential cause of beam-loss/partial beam-loss, orbit distortion or tune shift. To overcome the difficulty in quickly identifying such a deviation, which otherwise involved tedious manual process by analyzing the data corresponding to 117 power supplies for the ramping duration, a ramping verification system is developed. The system provides automatic verification of the correctness of ramping of all 117 power supplies participating in ramping along with and genration of the reports. This is implemented using SCADA and Matlab modules. Various sequential tasks are executed by these coordinating software modules as depicted in figure-1

Ramping verification algorithm
The algorithm was developed to verify that each Magnet Power Supply (MPS) has followed the Ramp profile as per the standard ramp file selected . The system verifies that :

• All the required Power Supplies had been selected for Ramping.
• All the selected Power Supplies had participated in Ramping.
• Ramp profile matched the standard profile.
