Following web based applications have been developed for indus subsystems developers, beam line users, operation crew members, system administrators and general users. These applications operate in the intranet environment using three tiers software architecture and mainly uses HTML, JavaScript, Java Server Pages (JSP), JavaBeans and SQL databases for designing its various building blocks. Java Server Pages, which act between client and data tier were chosen to implement the middle tier. Stored Procedures have been used by Java Beans for quickly retrieving the machine generated data stored in high availability databases.

• Indus OnLine Web Portal
• Indus Fault Log Book (FLogbook)
• Indus Operation Log Book (eLogbook)
• Beamline Booking Manager
• Electronic Planner (ePlanner)
• Machine Information Display System

This web portal has been developed for online providing the live, historical, and statistical data of Indus Accelerators in tabular, graphical and synoptical format over RRCAT-Intranet. More than 15,000 parameters logged in central database server can be queried and retrieved using this web portal. This site also provides the functionality to query and download the csv format raw data on local machine so that it could be used by other data analysis tools to understand the behavior of the machine. Some of the important functions of the portal are as follows:

• Beam loss probe
• Data diagnostics
• Multi parameter graph display
• Live synoptic display
• Beam trip analyzer
• 3D trend plotting
• Data download

FLogbook has been developed for tracking the faults occurred during round the clock operations of Indus-1 and Indus-2. Salient features of FLogbook are as follows:

• Accessibility from within Campus network (RRCATNet)
• Authentication using RRCAT Mail Server credentials
• Comprehensive dynamic device list
• Grab the screenshot in single mouse click (using snapshot module)
• Log the fault related information with attachment (e.g. image, doc, excel, etc)
• Email the logged fault with attachment to concerned persons
• Unique fault-id for every logged fault
• Search the logged faults according to date, system name, search string, etc
• Acknowledge & email the expert comments on the specific fault to other concerned persons
• Online fault statistics generation
• Restricted editing & deletion of fault entries
• Daywise report generation

Indus operation Logbook (eLogbook) has been developed for indus operation crew members for logging the operation related activities. Salient features of the eLogbook are as follows:

• Accessibility from within Campus network (RRCATNet)
• Authentication using RRCAT Mail Server credentials
• Only authenticated & authorized persons can enter & edit the records
• Provision to enter Image with details
• Fault entry in flogbook
• Automatic entry of statistical data in report
• Storing each entries with timestamp and user name
• Auto-grow spreadsheet for each sub sections
• Editing prohibited for entries older than one week
• Shift duty statistics generation
• Printer friendly Report Generation of older records for filing

Beamline Booking Manager Software has been developed for Indus beamline users for booking the beam for different dates and time slots. Some of the important features of this software are as follows:

• Provision for Beamline Booking, Editing, Approval, Deletion and Search
• Provision for Machine Shutdown Booking, Approval, Cancellation and Search
• Authenticated and authorized Service
• Secured with Captcha
• Configurable Permissions
• Both Rings Booking

ePlanner software provides the functionality for scheduling the day-to-day activity to be performed by the Indus operation crew members. The application also provides the functionalities for managing the system wise standing instructions and electronic notice (using eNoticeboard) which are displayed on Large Format Displayed installed at various places of Indus premises.

This web technology based system displays the information on large size display panels installed at various places of Indus-1 and Indus-2. This system displays the live and previous one hour historical data in tabular and graphical format. Information being displayed by this system currently includes live beam information, beam line usage status, current beam line bookings, work plan, standing instructions, ring pressures, orbit feedbacks and messages entered by operation shift in-charge.
