					                 Proposal to set up Radio Telescope outside Jing Xian Library

About our Project

We are a group of students from Hwa Chong Junior College doing a CenTaD project on
receiving radio waves from Sun and Jupiter. Our Teacher Mentor is Dr Lim Jit Ning and our
external mentors are Tan Peng Kian and Prof Phil Chan, both from NUS.

Our members are: Benny Lim (10S7F), Cai Shuting (10S64), Fang Ming (10S6C), Lam Bo Jun
(10S7F), Ong Seng Peing (10S7F), Szeto Kah Keong (10S7D)

Aim of Project

- to receive and analyse radio wave data from the Sun

- to receive and analyse radio wave data from Jupiter

Proposal

We wish to set up our radio telescope, over a course of a few weeks, at an open space with
minimal obstruction and interference.

This is so that we can receive sufficient data from the Sun and Jupiter to analyse and present
in the Singapore Science and Engineering Fair 2011.

We would like to set up our radio telescope outside the Jing Xian Library at Hwa Chong
Junior College.




                      Figure 1 Proposed set up location: outside Jing Xian Library
Reasons for Choosing the Place

- The open space is located at quite a high place in the school, and there is minimal
obstruction, e.g. trees and buildings.

- There is a sheltered area nearby where we can put our laptop / desktop to collect data
from the telescope.

- We can negotiate with the HC Strings Ensemble members to help lock our laptop and
equipment in the room.

- There is a power socket nearby, and it is convenient to provide power supply to our
equipment for it to run for a few weeks.

- It is easy for us to visit and check on the set up when necessary, as compared to if we set
up in places like rooftops, which are not readily accessible.

Additional Equipment Required

- Power Extension Cables
- Laptop (to loan from school)
- Table (to put our laptop on)

Set Up Details



          East                                                                                       West

                         Morning                                                     Evening
                                                                 Copper Antenna (7.0m long, East West direction)
                                                                 to receive radio waves from the Sun and Jupiter




         Strings Room
                                   Sheltered Area


                                             PVC Pipes (3.0m tall)


                                                                                            Dustbin with
             Laptop on
                                                                                          bricks/rocks to
               Table
                                   Cable (taped to ground)                               provide support




Figure 2 Proposed Setup (note: dustbin, bricks, PCV pipes, and copper antenna are available)
Proposed Time of Set Up

We propose to let the set up stand from 13 September 2010 (Term 4 Week 1 Monday) to 1
October 2010 (Term 4 Week 3 Friday).

The radio waves of the Sun can only be received after 12noon because in the morning, the
sun rays will be blocked by the building. We will let the set up run after 12 noon to 6pm to
collect data from the Sun.

The radio waves of Jupiter can be received usually from 4.00 am to 5.30 am. We will let the
set up run from 8pm to 8am to collect data from Jupiter.

Safety Precautions

We will position our radio telescope at the area not too close to the edge, so that in the
event that it collapses (although it is unlikely due to our strong foundation of bricks as
support), it will not fall to the 1st floor and injure people.

In the event of rain, we will disconnect the power supply to prevent short circuit of our
equipment. We will also monitor the weather forecast frequently to check whether it will
rain during the nights, so that we can disconnect the power supply before we leave school.

The cable connecting the antenna to the laptop will be taped to the floor. This is to prevent
passers-by from tripping over and injuring themselves.

We will set up a sign in front of the telescope to warn people from walking too close to the
telescope.



We earnestly wish that this proposal can be approved, so that we can set up as soon as
possible, and do the school proud in the 2011 Singapore Science and Engineering Fair.

Yours Sincerely,

Benny Lim (10S7F)
Cai Shuting (10S64)
Fang Ming (10S6C)
Lam Bo Jun (10S7F)
Ong Seng Peing (10S7F)
Szeto Kah Keong (10S7D)
